Hot-pack method
Wear plastic or rubber gloves while handling hot peppers. Prepare tomatoes, chile peppers, and onions as specified.
Combine all ingredients in a large saucepan. Bring to a boil while stirring, then reduce heat and simmer for 10 minutes.
Fill hot pint jars with hot salsa, leaving 1/2-inch headspace. Remove air bubbles, adjust headspace, wipe rims, and apply two-piece lids.
Process pints in a boiling-water canner for 15 minutes at 0–1,000 feet, 20 minutes at 1,001–6,000 feet, or 25 minutes above 6,000 feet. Cool undisturbed for 12 to 24 hours and check seals.
