    This ketchup actually comes close to the big brands in terms of taste, texture and colour. Using a slow cooker, this thick and tasty tomato ketchup practically cooks itself.

    1. Pour pureed tomatoes into slow cooker. Swirl water in empty tomato jars/cartons and pour into slow cooker. Add sugar, vinegar, onion powder, garlic powder, salt, celery salt, mustard powder, black pepper, cayenne pepper and whole clove; whisk to combine.

    Am amazed! This is excellent! I didn’t tweak the recipe - used slightly less sugar (I ran out!) and I used about 1/2 a tsp of cayenne (the ingredients list doesn’t tell you how much to use). Cooked it for 10 hours, then let it cool and it’s a perfect consistency. Will certainly do this again. Highly recommended. Thank you.  -  13 May 2018

    Wow! This recipe came out great. I have two little kids and wanted to make a ketchup without high fructose corn syrup, and to use in our homemade BBQ and sloppy joe sauces. It tastes just like the bottled stuff. I skipped the white sugar & put in 1/3 c of honey instead, to make it even less processed. Canned crushed tomatoes made it easier to strain at the end, and the consistency is pretty good. I would skip the added water next time when using the honey. This is a keeper! I'm so excited that I found this recipe & it was so easy using the slow cooker.  -  30 Jan 2014  (Review from Allrecipes US | Canada)

    This turned out great! I used minced green onions, garlic, and celery instead of the garlic powder, onion powder, and celery salt. I didn't puree it because I kind of like the chunky consistency. I think next time I will try peeled pureed tomatoes and cut the sugar a bit. All in all, easy and delicious!  -  20 May 2013  (Review from Allrecipes US | Canada)
