"This ketchup does come close to those name brands in terms of taste, texture and color. I've never had a tomato paste-based ketchup that I liked, so I decided to cook down crushed tomatoes instead. By using the slow cooker, we take most of the labor out of the process."

  1. Pour ground tomatoes into slow cooker. Swirl 1/4 cup water in each emptied can 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.
  2. Cook on high, uncovered, until mixture is reduced by half and very thick, 10 to 12 hours. Stir every hour or so.
  3. Smooth the texture of the ketchup using an immersion blender, about 20 seconds.
  4. Ladle the ketchup into a fine strainer and press mixture with the back of a ladle to strain out any skins and seeds.
  5. Transfer the strained ketchup to a bowl. Cool completely before tasting to adjust salt, black pepper, or cayenne pepper.

I have a question ( I have not yet tried this recipe). Could this be made in large amounts and then "canned" in a water bath like other veggies and fruits. I would love to make a big batch of ...

Chef John loved your video! I too am one more fool by making homemade ketchup, and I must say I'm sure glad I did it with your recipe. I used my own homegrown tomatoes, mashed and strained them...

Have not tasted it post-cooking, but it smells and tastes like good ketchup as it is cooking! Just wanted to note that the ingredient list does not include cayenne, yet the directions call for ...

Add me to the list of crazies. I have been making my own BBQ sauce lately so I've been going through quite a bit of catsup. Plus if I make my own catsup then my BBQ sauce is even more mine. My...
