Canning method
Wash and rinse pint canning jars; keep them hot until ready to fill. Prepare lids according to the manufacturer's directions.
Wear plastic or rubber gloves while handling hot peppers and do not touch your face.
If peeling the long green chiles, blister them in a 400°F oven or under a broiler for 6 to 8 minutes, or blister them on a hot range top. Place blistered peppers in a pan, cover with a damp cloth, cool, and peel. Finely chopped chiles usually do not need peeling.
Combine all ingredients in a large saucepan and bring to a boil, stirring frequently.
Reduce the heat and simmer, stirring frequently, until the sauce is thick, about 1 hour.
Fill clean, hot pint jars with hot taco sauce, leaving 1/2-inch headspace. Remove air bubbles, adjust headspace if needed, wipe jar rims, and apply prepared lids and rings.
Process pints in a boiling-water canner for the time specified for your altitude: 15 minutes at 0–1,000 ft, 20 minutes at 1,001–6,000 ft, or 25 minutes above 6,000 ft.
