Gerbie, it is an old family recipe, but I'm not much for secrets when good food is concerned!
Terry Hot Sauce (My maiden name)
1 gallon tomatoes
2 c. vinegar
1/2 c. sugar
1 1/2 T. salt
2 T. garlic salt
5 large onions
5 large bell peppers
1 c. jalapeno peppers (minced)(give or take a few, depending on your heat tolerance)
You can either use and old fashioned grinder or a food processor to chop all ingredients.
Cook until fairly thick(don't ask how long!) Then can as you prefer. I boil jars, lid flats, put hot sauce in while still very hot. I have never had issues with the lids not sealing.
