Canning method
Combine ingredients in a large saucepan; bring to a boil over high heat while stirring frequently.
Reduce heat and simmer 20 minutes, stirring occasionally.
Ladle hot salsa into hot pint jars, leaving 1/2-inch headspace. Remove air bubbles, adjust headspace, wipe rims, and apply lids.
Process pints in a boiling-water canner using the altitude-adjusted processing time from the source.
