I have a few salsa recipes that I mix and match. Here is my favorite one:
2 large onions
14 cups tomatoes
8 green or red sweet peppers
4 cloves garlic
1/2 cup sugar or add more to taste
3 tablespoons salt
1/2 tsp. oregeno
1 tsp. garlic powder
1.2 tsp cumin
1/2 cup vinigar
3 bay leaves
1/2 can mexired peppers- I substitute fresh hot peppers but you could leave this out if you don't want it too hot
2-3 cans tomatoe paste
Cook for one hour. Mix 5 tablespoons corn starch with a little bit of water until smooth. Add to salsa mixture and cook 5 more minutes. Pour into jars.
