Here is the recipe that I've used to can hot sauce for at least 15 years. I had an older neighbor (she could be my grandmother) show me how to can. One of the best skills I've ever learned!
Hot Sauce
16 cups fresh cored, peeled, and chopped tomatoes
3 cups chopped onion
1 cup chopped jalapeno peppers (more or less depending on the heat of the pepper and your tolerance for heat)
1/4 cup salt
1/3 cup sugar
2 cups vinegar
Cook down until you get the consistency you like. This can take about 1 1/2 hours to 2 hours. Seal in prepared jars. Makes about 8 pints.
This is before the cooking begins.
While cooking.
All sealed and ready to store. I only had a partial amount of tomatoes ready so it made a smaller batch. That's okay though, no tomato is ever wasted around here!
