A: No. In addition, to using ingredients in the right amounts, the jar size is important. Your recipe will tell you what size of canning jar to use. Credible and standardized salsa recipes will instruct you to use pint jars and give processing times for only pint jars. There are no currently research tested guidelines for processing salsa in quart jars. If the recipe calls for pint jars and does not give directions for quarts jars don’t use them as they will be under processed and result in unsafe product. There are no formulas for extending the processing time for a larger jar.
