Learn how to make homemade ketchup from canned tomatoes.
Avoid artificial ingredients.
Take a look at your store bought ketchup ingredients. High fructose corn syrup was the second ingredient on the brand I was using. That is when I decided to investigate canning my own homemade ketchup.
I tried several times before I came up with this recipe that finally met with the approval of my crew.
Remember to use a tested recipe. You can adapt the seasonings, but don't mess with the ratio of vinegar and tomatoes and any other vegetables. It is the acidity of the recipe that makes it safe for a water bath.
This is a pickled item. Even though you may not think of homemade ketchup as a pickled item it falls in that category in home canning. The vinegar added makes the acidity of this recipe. I adapted the recipe from the Ball Blue Book for this version. I adapted the seasonings.
Ketchup can be processed safely in a Water Bath Canner
This makes about 3 pints which is a small batch. It can be processed in a water bath canner if you want to store it on the shelf. Or you can refill your ketchup bottle and store in the fridge.
If you like it, double it the next time. That way you can process 6 pints. I don't like running a half full canner. Seems so inefficient.
Gather your canning supplies
Start by preparing jars, and get water in your canner heating.
(see Water Bath Canning for full directions)
Combine 1 quart tomatoes, onion, sweet pepper. Simmer until vegetables are soft.
Press all tomatoes, and tomatoes with onion and sweet pepper mix, through a food mill to remove seeds and/or skins.
Bring to a boil in a stock pot. Boil rapidly until thickened, stirring often. It will reduce quantity by half. This may take an hour or so.
Add vinegar, salt, sugar and other seasonings. Add cinnamon stick.
Place sauce in a slow cooker on high with the cover removed. Cook until thickened to your desired consistency. Again stirring often. This may take another hour or even several hours.
Remove cinnamon stick.
You can then put into a jar and refrigerate for use or you may process in pint jars. I saved my last ketchup bottle from the store and refill it from this recipe.
If you want to process for storage on the shelf use the following directions.
Pour hot ketchup into hot jars leaving 1/4 inch head space.
Remove air bubbles with a plastic knife or other small tool. I like to use an orange peeler. Wipe rims clean and process according to water bath canning directions.
