Caution: Canning any salsa recipe containing cornstarch and/or not expressly tested by the USDA may be at risk for botulism or other microbial contamination. If you want to thicken your salsa, it's best too pour off the excess water after opening the jar and add the thickening agent then.
4 quarts tomatoes, skinned and chopped
5 medium onions, chopped
3 green peppers, chopped
6 to 7 jalapeños or 1 jar (6 ounces)
7 teaspoons canning salt
1⁄2 teaspoon garlic salt

In large kettle, combine tomatoes, onions, green peppers, jalapeños, salts and sugar. Bring to a boil, and boil 5 to 7 minutes. Mix cornstarch and water; add to tomato mixture. Boil another 5 minutes, or until fairly thick.
