Quick Answers



Can tomato products like salsa, chili sauce, tomato paste, tomato relish, etc., be canned in a boiling-water canner?

A general recommendation for all tomato products cannot be made, as recipes combining low-acid vegetables with tomatoes vary widely in ingredient proportions. Products like these depend on added acid or adequate heat processing for safety. When making these products, use reliable, scientifically tested recipes found in current University Extension publications (1989 or later). Do not add extra vegetables, cut down on any ingredients, or short-cut the heat processing in any recipe for home-canned tomatoes or tomato products. See GH 1456 "Tantalizing Tomatoes" for safe procedures for many tomato products.
