Instructions
Wear rubber gloves while handling hot peppers and avoid touching your face. Wash peppers. Slash small whole peppers or quarter large peppers.
Blanch or blister peppers at 400°F for 6 to 8 minutes or over a burner until skins blister. Cool, peel, and flatten small peppers.
Pack into hot half-pint or pint jars, leaving 1/2-inch headspace.
Bring vinegar, water, salt, sugar, and garlic to a boil; simmer 10 minutes and remove garlic. Cover peppers with hot liquid, maintain 1/2-inch headspace, remove bubbles, wipe rims, and apply lids.
Process in a boiling-water canner: 10 minutes at 0–1,000 ft, 15 minutes at 1,001–6,000 ft, or 20 minutes above 6,000 ft. Cool 12 to 24 hours and check seals.
