Homemade ketchup for canning is one of those rare recipes that actually tastes better when made at home!
Ketchup is America’s favorite condiment when it comes to backyard BBQs and cook-outs.
That also happens to be when tomatoes are plentiful, so this homemade ketchup recipe uses fresh tomatoes!
Ketchup is a weakness of mine, especially, that I find myself craving at odd times.
I’m convinced my body is craving the licopene that is found in high concentrates in ketchup…or at least that’s what I tell myself.
History of homemade Ketchup
Ketchup has a long, interesting history. It began as a fish and seafood pickle that English settlers brought back to England from China in the 18th century.
Once in the UK, the fish was substituted for mushrooms, and the word “cat-sup” changed to mean any thin, brown, savory sauce.
Mushroom ketchup was used in the United States as early as 1770’s.
By the early 1800’s, tomato ketchup had grown in popularity, but recipes for Oyster Catsup, Tomato Catsup, Mushroom Catsup, and even Walnut Catsup can be found in my favorite historical cookbook, The Virginia Housewife.
Sugar wasn’t added to the original ketchup recipe until it began to be commercially produced and sold in markets.
It was added as a preservative, and gives us that sweet, tangy taste we know today.
How to Make Homemade Ketchup
This homemade ketchup recipe is delicious, painfully easy to make, and will stand up to the pickiest eaters in your household.
Simply throw together fresh tomatoes, vinegar, brown sugar, water, salt, onion powder and garlic powder into your Instantpot on slow cooking or a crockpot.
Cook on low for several hours. The longer you let it cook the more the flavors meld and develop. Give it all day if you’ve got time!
Blend in batches with a blender or with an emersion blender until smooth and put it back in the pot to reduce further.
Below I’ve added both the recipe for a single batch that will keep in the fridge for a week or a big batch for canning roughly 7 pints, depending on consistency.
To can your homemade ketchup, simply fill sterilized mason jars, affix lids and rings and process in a hot water bath for 15 minutes. It is high in acid so it can be water bath canned instead of pressure canned.
