This is a guest post by Melanie Zook, MA, RD, LDN. She is the blogger behind Fresh Start Nutrition where she offers wellness classes, workshops, pantry makeovers, and nutrition consultations. She lives here in the Charlotte, NC area, and I thought you all would enjoy her homemade ketchup recipe from her new DIY Kitchen Cookbook!
Hi there, I’m Melanie, and I think the kitchen is the perfect place to do it yourself (DIY).
Why DIY in the kitchen?
- YOU are in control.
You know exactly what’s going into your food – no preservatives or artificial flavors, colors, or sweeteners, just whole, clean, healthy foods instead of processed foods that are full of unnecessary additives.
– - You’ll save time and money, as well as space in your pantry and refrigerator.
Once you stock up on the ingredients you’ll need for a DIY kitchen, you won’t have to buy as many premade staples and you can save yourself the extra errands. Spend some time putting together the make-ahead mixes and you’re done.
– - It’s green.
You can skip the excess packaging of premade, processed foods.
– - It’s worth it to make some of your meal and snack staples.
They take a matter of minutes using ingredients you probably already have on hand. (But some DIY recipes out there just aren’t worth the time and hassle if you can already find affordable clean versions in the store.)
These reasons are exactly what inspired me to put together my new DIY Kitchen Cookbook*. It covers how to Make Your Own Clean & Healthy Make-Ahead Mixes, Seasoning Blends, Snacks, Breakfasts, Condiments, Dressings & Drinks with copycat recipes that are cleaner, healthier, and more budget-friendly versions of what you’d normally buy in a grocery store. The recipes are designed so you can tweak them to fit your family’s preferences or swap out ingredients to make them allergy friendly.
Homemade Ketchup in the Slow Cooker
Let’s start with ketchup. It’s a kid-friendly kitchen, restaurant, and picnic staple, but the bottled, store-bought version is one of the condiments highest in sodium and sugar (often in the form of high fructose corn syrup). And some of the new reduced sugar varieties are made with artificial sweeteners. By making your own, however, you can control how much salt is added and skip the processed sugar altogether by using honey as the sweetener.
Homemade ketchup makes a perfect summertime hostess gift. Double the recipe, pour into mason jars, and tie on a bow.
It also freezes well (leave headroom if freezing in jars to allow for expansion). Or freeze in an ice cube tray so you can thaw out individual portions when you need them for serving food or when making other recipes, such as barbecue sauce.
Many people are pretty loyal to their ketchup brand, so I knew this recipe would be a tough one to develop. But my Heinz-loving husband from Pittsburgh approves. I hope you do too!
Homemade Ketchup in the Slow Cooker
From The DIY Kitchen Cookbook by Melanie Zook, MA, RD of Fresh Start Nutrition
Ingredients
- 1 28-oz can tomato puree
- ¾ cup white vinegar, Look for white vinegar derived from corn or rye or try apple cider vinegar.
- ½ cup honey
- 1 ½ teaspoons salt, kosher
- 1 teaspoon onion powder
- ½ teaspoon garlic powder
- 1/8 teaspoon celery salt
- 1/8 teaspoon ground mustard, mustard powder
- 1/8 teaspoon cloves, about 3 cloves
- pepper, and/or cayenne pepper to taste (optional)
Instructions
-
Add all ingredients to a slow cooker.
-
Cook on low for 8 hours or until thick.
-
Store in a glass jar or a squeeze bottle in the refrigerator or freeze.
Recipe Notes
• We recommend organic ingredients when feasible.
• Use the same measuring cup for the honey that you did for the vinegar. Honey slides out of a wet measuring cup much better than out of a dry one.
• Grind whole cloves using a mortar and pestle or with the flat side of a chef’s knife.

July 6, 2015 at 11:05 amCool recipe! How long does the ketchup last once it is made?
Melanie Zook
July 6, 2015 at 12:03 pmI’ve kept it in my fridge at times for at least a month with no problems. To avoid waste, though, I usually double a batch, then freeze it in pint or quart sized jars (leave headroom), then thaw out a jar to refill a squeeze bottle as needed.

July 6, 2015 at 11:24 amJust a bit of advice for those of you who haven’t made your own condiments before. I have done so for years because of HFCS and food allergies, and the one main thing I have taken away from this is to always *taste* your condiments as you go… especially when adding seasonings. I would also cut way, way back on the cloves in this recipe. I don’t know why, but the taste of clove is very strong in my homemade ketchups if I follow the recipe. After trial and error, I now leave it out almost entirely, and sometimes I just simmer a few whole cloves in the mixture in a cheesecloth bag and take them out before putting the ketchup in a jar. You can always add more, but it’s very hard to subtract… and the taste of cloves is something people either love or hate. If you’re not sure, you might want to leave them out until the end, and taste adding a tiny bit at a time, stirring well in between.
Melanie Zook
July 6, 2015 at 12:07 pmGood tip! Our testers really liked the 1/8 teaspoon ground cloves, but definitely tweak the recipe as you go to suit your taste. I like the cheese cloth idea–a nice way to “infuse” the flavor.
Renee Laning
July 6, 2015 at 11:29 amIf I wanted to use my fresh or my canned tomatoes from my garden, how would I do that instead of the tomato puree?
Melanie Zook
July 6, 2015 at 12:08 pmI would give that a try! Remove the skins and puree well. The slow cooker method really helps to thicken the puree, but you may want to add more time if it’s too liquidy with home canned or fresh tomatoes.
Critical Reader
July 7, 2015 at 9:04 amMy mathematical solution: according to the USDA food database, tomato puree contains 12 % dry matter and fresh tomatoes contain 5 % dry matter. Hence, to mimic the recipe, you might want to start with 67.2 oz fresh tomatoes (= 12/5 * 28 oz tomato puree). However, by law tomato puree can have a dry matter between 8 and 24 %, which adds a huge factor of uncertainty to my calculation. BTW, if my math is not off, the recipe here is actually higher in sugar than commercially available tomato ketchup ;-)
Melanie Zook
July 7, 2015 at 9:37 amOh, and of course you could always tweak the recipe and decrease the amount of honey.
Critical Reader
July 7, 2015 at 10:25 amCertainly. I am actually not too concerned about sugar in ketchup as it is a condiment and is not eaten by the pound – at least not by adults. Have you ever played around with the sugar-tomato-vinegar ratio? I am wondering how far you can go down with sugar/honey until it affects the taste or consistency too much.
Melanie Zook
July 7, 2015 at 1:34 pmI did, but didn’t take good notes. :( Just a little more of this and a little less of that!
Barbara
July 6, 2015 at 1:07 pmI’m getting ready to start whole30, (no sugar of any kind) I wonder if dates can be used in place of honey?
Melanie Zook
July 6, 2015 at 1:38 pmMaybe you could try making a making a date “syrup” in your blender first, then use that as you would the honey.
Cindy
July 6, 2015 at 3:52 pmHi Melanie,
I cannot wait to make this! I’ve pinned ketchup recipes before, but never got around to actually making any of them. When you mentioned the slow cooker, you said my magic words :) My kids eat a ton of ketchup and I love the ingredients you’ve used. Thanks for the great post – it’s pinned and waiting for my prep day!
Melanie Zook
July 6, 2015 at 6:27 pmI’m so glad to hear that, Cindy! I hope the kids (and you!) love it.
Amanda
July 6, 2015 at 4:54 pmIs there any reason you couldn’t can this and make it shelf-stable? (the way you would with bbq sauce or preserves).
Melanie Zook
July 6, 2015 at 6:28 pmI’m not a canning expert, but I would think it would can just like any other canned tomatoes!
Stacy
July 6, 2015 at 5:57 pmThis recipe sounds great – my son thinks ketchup should be the bottom of the food pyramid. What size slow cooker did you use?
Melanie Zook
July 6, 2015 at 6:37 pmStacy, we have a small one and a “big” one and I use the small one for this. It’s 4 quart.
Stacy
July 7, 2015 at 1:36 pmThank you!
Melanie Zook
July 6, 2015 at 6:37 pmAnd I hope your son approves! :)

July 7, 2015 at 9:41 amCan you make this on the stove if you don’t have a slow cooker?
Melanie Zook
July 7, 2015 at 1:35 pmYes! Just simmer (very low heat) until it thickens and the flavors meld.
Amy
July 7, 2015 at 9:46 amYou must have read my mind….I was just thinking about this over the weekend after becoming frustrated with not finding any ketchup in the stores without sugar or artificial sweeteners (even found one that had a salt substitute?) Thank you so much; cannot wait to try this!!
Melanie Zook
July 7, 2015 at 1:36 pmGreat timing! Hope you found your new ketchup!

July 7, 2015 at 9:48 amHow long does this last in the fridge?

Michelle
July 7, 2015 at 11:59 amDoes anyone know if this could be made in bulk and canned?
Melanie Zook
July 7, 2015 at 1:40 pmI often make a double batch, then freeze it in pint or quart sized jars. Then I’ll thaw out a jar as needed, then transfer to a squeeze bottle in the fridge. While I’m not a canning pro, I would think it would can just like any other tomato product. Hope you like it!
Leslie
July 7, 2015 at 1:44 pmWhy would you use White Vinegar which is made from coal tar? It is not real food by any stretch of the imagination. Have you tried real Apple Cider Vinegar?
Melanie Zook
July 7, 2015 at 1:57 pmI’m glad you commented–I should have suggested in the recipe to stick with Heinz white vinegar (ironically, it’s a DIY ketchup recipe) or certainly give apple cider vinegar a try (another reader also plans to do this because her son cannot have white vinegar)–that would give it a good flavor AND I would even try decreasing the honey. Let us know if you try it!
Melanie Zook
July 7, 2015 at 1:50 pmNo Kindle needed! I’ve received a few messages on my Facebook page asking if the e-cookbook comes in any other formats since you don’t all have a Kindle. The good news is you do NOT need a Kindle device–you can get an free app for your desktop, laptop or most other gadgets (like a smartphone or tablet) here: http://amzn.to/1ruJBCz or in your gadget’s app store. Then, when you buy and download the e-cookbook, you just read it right on the Kindle app. Hope that helps!

May 2, 2019 at 10:33 amI read a post said to add hot ketchup to warm pint jars 1/2 inch head space boil bath for 15 minutes.
VICKI L MORRIS
May 2, 2019 at 10:37 amI like reading the recipe for your ketchup. Other homemade recipes have you constantly needing to stay on top of preparation. With the slow cooker you can other items while waiting for the ketchup to make. Love the idea.
ShastaJoe
July 7, 2015 at 4:09 pmI’d love to make this but I have one question that’s frustrating me: is tomato puree the same thing as tomato paste, or the same thing as tomato sauce, or some third tomato product that I never see in the store: Inquiring minds and all that… :)
Critical Reader
July 8, 2015 at 7:44 amTomato paste and tomato puree are similar, but tomato paste is more concentrated (http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfCFR/CFRSearch.cfm?fr=155.191).
There is no standard for tomato sauce, there is just a minimum amount of tomato set out (http://www.fda.gov/ICECI/ComplianceManuals/CompliancePolicyGuidanceManual/ucm074470.htm).
Melanie Zook
July 8, 2015 at 7:50 amTomato puree is one of the canned tomato products in your canned tomato aisle. My “regular” grocery store has it in some of it’s usual brands: Hunt’s, Contadina, Cento, etc. Many recipes out there use tomato paste, and I tried that, but found a much more ketchup-y flavor with puree.
Melanie Zook
July 8, 2015 at 7:50 amOops! Its usual brands. :)
ShastaJoe
July 8, 2015 at 5:53 pmThank you, Critical Reader and Melanie, for the quick response! I don’t recall ever seeing tomato puree on the local grocers’ shelves, but I don’t think I’ve ever looked for it, either. It would be quite ironic if it isn’t available here in California where we’re up to our waists in tomatoes this time of year! :)
Melanie
July 7, 2015 at 8:51 pmYippy! I’ve been wanting to use up my tomato puree but hadn’t taken the time to find a good recipe. I’m excited to make ketchup this weekend! Have you ever made Worcestershire sauce? I have avoided buying it for months because of the extra unwanted ingredients but have some recipes I would love to put it in. I’m sure I can Google it and find a recipe but thought I’d ask the real food expert first. :)
Melanie Zook
July 8, 2015 at 7:53 amNot sure if Lisa has, but I haven’t made that yet. My parents used to. Maybe it’s a good recipe to include in the next edition of my DIY Kitchen Cookbook! I’ll get on that. :)
Dolores
July 8, 2015 at 12:57 amHi Melanie,
This recipe sounds delicious. I like to make all my dressings and condiments but I have never tried ketchup. My husband loves ketchup so I’ll have to give this one a try.
I would also recommend using organic apple cider vinegar. I use it to substitute for white vinegar in all my recipes and it does taste delicious.
This recipe could be canned with no problem. When canning tomatoes it is recommended to add some citric acid to make sure there is sufficient acid to can safely. Since this recipe has vinegar there should be no problem with insufficient acidity.
Melanie Zook
July 8, 2015 at 7:47 amHope you’re able to add this to your list of homemade condiments! Good tips–a reader commented that she was going to use apple cider vinegar too. I think that would add a good flavor and you may even be able to cut down on the honey. Am trying that next time!
Faith
August 5, 2015 at 4:48 pmThanks. I was just going to ask if it could be canned for gift giving at the holidays. Ball suggests canning ketchup for 15 minutes in a boiling water bath. Leave half-inch head space. I’m assuming this can be made in larger quantities?
Melanie Zook
August 5, 2015 at 5:11 pmThanks, Faith! I haven’t made it in larger quantities, but I don’t see why it couldn’t be. You may need to add more time to the simmer for it to thicken enough.
Leora Valdez
July 9, 2015 at 12:02 pmHi, I don’t have a kindle – does the condiment book come any other way?
Melanie Zook
July 9, 2015 at 1:58 pmThanks so much for your interest in the cookbook, Leora. The good thing is, you don’t need a Kindle–you can get an app for any computer or gadget (iPad, etc.) for FREE here http://amzn.to/1ruJBCz or in your gadget’s app store. Then, when you buy the Kindle book, it’ll download to the app and you can read it as an e-book. Hope that helps!

July 11, 2015 at 6:18 pmCan I use fresh tomatoes instead of canned puree to make it truly real food?
Melanie Zook
July 13, 2015 at 9:54 amI don’t see why not! While I haven’t tested it this way, I would think that you would steam the tomatoes to make them easy to peel, puree well, then add some time to the slow cooker method to allow more water to cook off until it is the consistency of ketchup (fresh tomatoes may be more watery).
Sylvia Charlton
August 5, 2015 at 7:46 pmI was going to ask about fresh tomatoes too – I don’t used canned tomatoes, spaghetti sauce etc because of the BPA in the can lining. So I will cook up fresh tomatoes and strain the seeds and skin out and go from there. I might add the skins and seeds to soup. Thanks for the recipe.
xymonau
July 12, 2015 at 5:25 amI just wish you could do one without the vinegar – using tamarind paste or citric acid.
Melanie Zook
July 13, 2015 at 9:55 amA few readers plan to use apple cider vinegar. You may even be able to cut down on the honey a bit that way.

July 15, 2015 at 12:15 pmEarlier I was asking about tomato puree vs strained tomatoes. I see there is some additional information in the comments. Thanks ladies. And I agree using apple cider vinegar would be great! I have also found some tomato products in glass jars (available in the US, sorry I shared products that I found in my Canadian store only and not organic). Bionaturae has Organic Tomato Paste and Strained Tomatoes. They are from Italy. Also Jovial has Organic Diced, Crushed and Whole tomatoes. They are in the US. I found these on a site where I order other organic foods, and health related things.
Sandra Mort
July 16, 2015 at 3:24 pmHave you tried making it without honey? I used to be able to get unsweetened ketchup at some point, but I haven’t seen it for years. I don’t really like regular ketchup because it’s too sweet.
Melanie Zook
July 18, 2015 at 2:35 pmI haven’t tried that. But I don’t see a reason that you couldn’t either cut way back on it or cut it out completely.
Michelle
July 20, 2015 at 11:29 pmI just took my ketchup out of the slow cooker and it is very thin…a little thicker than tomato soup. Will it thicken up in the fridge? (I hope!)
Melanie Zook
July 21, 2015 at 8:09 amWhile it will thicken a bit more, it should be thicker than that when it’s done (the photo shows the exact product). (The puree you started with would typically be thicker than that too.) You could try letting it cook longer to cook some water out, or simmer it longer on the stove?
Synisterkat
August 5, 2015 at 6:21 pmDo you leave the lid off the slow cooker? Curious as to how it would thicken without doing so.
Melanie Zook
August 6, 2015 at 9:53 amYou certainly could. The slow cooker I use does not seal, so between some steam escaping that way and the amount of water that condensed (and the fact that the puree is somewhat thick already), it cooked to the consistency of what you see in the photo.
Synisterkat
August 6, 2015 at 8:08 pmThank you!
Nikki
August 5, 2015 at 8:09 pmHi there could u replace sumthing with the honey? What would the nutritional info be ? I don’t eat alot of carbs ? Thanx!! :)

August 6, 2015 at 9:55 amHi Nikki, you could try decreasing the honey. I haven’t run the nutrition numbers on this exact recipe yet!
Loreen
August 6, 2015 at 10:07 amI want to make the tomato puree from homegrown tomatoes, have you tried that?

August 10, 2015 at 1:37 pmCan you substitute Apple Cider vinegar instead of while vinegar?
Melanie Zook
August 10, 2015 at 1:42 pmYes, Emily–a few readers were going to try that. It may change the flavor a bit–in a good way, I’m sure–and you may even be able to cut down on the honey a bit. Let us know how it comes out!
Nikki
August 10, 2015 at 9:03 pmCan you can this using a water bath?
Melanie Zook
August 11, 2015 at 7:55 amHi Nikki–I’m not a canning expert, but I would think it could be canned as you would other tomato products. One of the commenters above gave some info…I’ll see if I can find it.
karen Foley
August 11, 2015 at 6:52 pmI made this a week or so ago. I LOVE ketchup on oven fries, and this is really tasty! I put it in my Organic H***z bottle. No one can tell that it’s not the original contents.
Melanie Zook
August 12, 2015 at 6:41 amGood idea! And glad you like it!
Dina
August 13, 2015 at 3:25 pmIf I double the recipe, do I need to cook it longer? Thanks!
Melanie Zook
August 15, 2015 at 1:44 pmHi Dina–while I haven’t paid attention for how MUCH longer, yes, I did let it simmer longer and just kept checking on it to see how the texture was doing.
Jennifer Love
August 18, 2015 at 4:50 pmCould I subsitute tomato paste for the puree?
Jennifer Love
August 18, 2015 at 4:52 pmI meant sauce instead of paste, sorry
So… Could I sub tomato sauce for the puree?
Melanie Zook
August 19, 2015 at 8:10 amHi Jennifer–I haven’t tested it this way yet. If you do try it, you would need to simmer it longer to cook more of the water out. Let us know how it works!
Katie
September 22, 2015 at 8:55 pmIs there an actual physical book we can purchase? I can’t seem to find anything on amazon? I can’t do technology in the kitchen :)
Mariah
September 23, 2015 at 7:43 amI’m wondering the same thing. I just can’t work well with my phone or tablet while cooking, the book just works better for some reason. But on Amazon it looks like it’s only digital right now.
Melanie Zook
September 24, 2015 at 11:20 amYes, only a digital version, Mariah. :( Thanks for your interest, though!
Melanie Zook
September 24, 2015 at 11:19 amHi Katie! Unfortunately, it’s only an e-book. While you do NOT need a Kindle to download and read Kindle books (get a free app for any device here: http://amzn.to/1ruJBCz), it sounds like that doesn’t help. :(
Danielle
September 23, 2015 at 8:22 amHi, how long and at what temp. do you stove cook this? Thanks!
Melanie Zook
September 24, 2015 at 11:21 amHi Danielle–I haven’t tested it on the stovetop yet, so I’m not positive. But I would keep it on low (or my stove has a ‘simmer’ option) and keep any eye on it.

Lori
September 23, 2015 at 4:23 pmWhere do you buy tomato puree. I have never seen in in a store.
Melanie Zook
September 24, 2015 at 11:24 amHi Lori–my store has the Cento brand, but Hunt’s and Contadina also makes a puree. Even better, Muir Glen Organic is available on Amazon if you’re an online shopper!
Val
October 5, 2015 at 6:00 amCan you use fresh tomatoes?
Melanie Zook
October 5, 2015 at 7:54 amHi Val–I haven’t tested it that way, but it sounds like some readers planned to make it with fresh tomatoes. You can see some of the info in their comments. Overall, it sounds like you would need to skin them as you would for other tomato products, then add more cook time to cook off more liquid (water). Let us know how it goes!
Tiffany
November 2, 2015 at 3:20 pmMine came out a lot darker and did not taste good. :-(
Melanie Zook
November 2, 2015 at 3:24 pmSorry to hear that! :(
Melissa
November 21, 2015 at 2:41 pmCould you do this with tomato paste instead and just add some liquid?
Melanie Zook
November 22, 2015 at 7:56 amThe first time I made it, I used tomato paste and it was too, well, tomato-y. But I probably just used too much! So if you give it a try, just go light on the paste.
Cheryl Weldy
March 19, 2016 at 1:08 pmSeems like a lot of salt

April 23, 2016 at 12:14 amI made this today and thought it was very good. Will be our family’s new ketchup. Thank you.

April 23, 2016 at 7:43 amI am happy to hear that! Thank you for the feedback–hope you and your family enjoy it at all your summer picnics!
Lena
May 21, 2016 at 10:47 amcan this be canned in a water bath versus freezing?
Melanie Zook
May 28, 2016 at 12:20 pmHi Lena–I’m not a canning expert, but I don’t see why not? Let us know if you give it a try!
Pam
June 15, 2016 at 8:40 pmI plan to give this as a small gift to coworkers. Could it be left unrefrigerated for 5 or 6 hours?
Melanie Zook
June 19, 2016 at 1:24 pmWhat a good idea! I would think so, but to be extra safe, you could freeze the jars then they’d thaw out by that time, all while keeping it chilled. Hope they love their gift!
Hannah
July 1, 2016 at 5:20 amwould you be able to can this via water bath or would you need to pressure can it???
Melanie Zook
July 1, 2016 at 7:23 amHi Hannah–I’m in no way a canning expert, but I don’t see why not? But I have only ever frozen it, not canned it. There have been a lot of other canning comments on this post, so I wonder if anyone else has tried it!

July 1, 2016 at 5:28 pmI would be concerned with canning because of the honey in it. I am not an expert but have canned and pressure canned many times, and I believe honey is one ingredient that is not supposed to go in a canning recipe. You could check the USDA website on canning to be sure!

July 2, 2016 at 7:14 amI’ve kept it in my fridge at times for at least a month with no problems. To avoid waste, though, I usually double a batch, then freeze it in pint or quart sized jars (leave headroom), then thaw out a jar to refill a squeeze bottle as needed.

July 24, 2016 at 2:41 pmI have to watch my salt. What could I substitute for tomato paste as it is high in sodium. I would have to leave out the salt also in the recipe and use celery seed not celery salt. I can’t wait to try it. I have only found on version of no salt ketcup and only one store sells it. Can’t wait to have my own. Thanks!

July 24, 2017 at 9:09 pmI didn’t know that this recipe called for tomato paste…

July 24, 2017 at 9:58 pmIt doesn’t! But you could add it if you’d like and experiment with it.

September 1, 2017 at 12:28 pmHi Mandy! There is no tomato paste in this recipe, so you should be good to go. Enjoy!

July 28, 2016 at 3:04 pmIt uses tomato puree, not paste, so hopefully you’ll be able to keep it low sodium that way. Hope you like how it turns out!

October 15, 2016 at 8:30 pmStore-bought ketchup tastes like chemicals and sugar to me, so I’ve been on a mission to make my own. I’ve tried several recipes! This is my current favorite. Thank you! I cook it on high for 8 hrs with no top on the CP to get it to the consistency I like. YUMMY! My family loves it.

January 4, 2017 at 7:45 pmI just made this, and had it in my crockpot on low for 10 hours but it was still pretty thin. It was also darker, had a saucy consistency, and had a very strong tomato sauce + vinegar taste. :(

February 20, 2017 at 5:10 pmHi KATYW, I’m not a canning expert, but I think based on a lot of the comments, some readers have given it a try. I would think it would work well. Good luck and I hope you like it!

August 31, 2017 at 11:07 amThanks for the recipe. I personally liked the taste of the ketchup and I’m not one to use it. Now the Heinz lovers didn’t care for it. I do have to mention that you should cook it on low in the Crock-Pot for 8 hours with the lid off. I did the recipe exactly the way it said to and it was still soupy because the steam built up inside the lid and poured back down into the ketchup. I then took off the lid and cooked it on low for 8 hours and it came out to a perfect consistency. I do advise stirring this mixture occasionally so you don’t get a crusty build up around the edges.
sionally so you don’t have a crusty build up around the edge.

October 15, 2017 at 2:17 pmThis looks like a great recipe and I chose it to use as a start up recipe. I made my changes to suit our tastes. I subbed honey for reg corn syrup and added about 1/3 cup sugar. I also added more salt, black pepper and cayenne pepper. I decided not to use my slow cooker and added one can of tomato paste and simmered for about 30 minutes. All the other spice measurements were spot on. Thanks for sharing your recipe.
