adding acid to salsa

Asked September 3, 2014, 7:45 PM EDT

Do I have to add an additional acid to canned salsa? My recipe is roasted tomatoes, roasted jalapenos, onions, cilantro and garlic salt, and I don't like the flavor of vinegar or lemon juice in it.

Good Afternoon,

Thank you for your important question. Yes, salsa must have acid (vinegar, lime juice, lemon juice) added to it to make it safe for canning. If acid is not added, there would be a potential for botulism to grow since the ingredients are mostly all low-acid foods. You may find some great canned salsa recipes in our "Salsa Recipes for Canning" publication available at:

If you do not like the acid in the salsa, you may freeze it or eat it fresh.
