Mexican Tomato Sauce — NCHFP
Ingredients
- 2 1/2 to 3 pounds chile peppers washed, blistered, peeled, seeded and chopped
- 18 pounds tomatoes peeled, cored and coarsely chopped
- 3 cups onions chopped
- 1 tablespoon salt
- 1 tablespoon oregano
- 1/2 cup vinegar
Equipment
- 1 Pressure canner Dial-gauge or weighted-gauge model.
- 7 Quart canning jars The source also provides a pint process; use the time for the selected jar size.
- 1 Nonmetallic bubble remover
Directions
- Read the pressure-canner manufacturer's instructions and the linked NCHFP pressure-canning guide. Wear gloves while handling hot peppers and keep your hands away from your face and eyes.
- Wash and dry the chiles. Slit each one so steam can escape. Blister skins for 6–8 minutes in a 400°F oven or broiler, or over a burner protected by heavy wire mesh. Cool under a damp cloth, peel, discard seeds and chop.
- Wash the tomatoes. Dip them in boiling water for 30–60 seconds, until skins split, then transfer them to cold water. Slip off skins, remove cores and chop coarsely.
- Combine the prepared tomatoes and chiles with the onions, salt, oregano and vinegar in a large saucepan. Bring to a boil, cover and simmer for 10 minutes.
- Fill hot jars with hot sauce, leaving 1 inch headspace. Release trapped air, restore headspace, wipe rims and fit lids.
- Dial-gauge canner: process pints for 20 minutes or quarts for 25 minutes at 11 psi from 0–2,000 feet; 12 psi at 2,001–4,000 feet; 13 psi at 4,001–6,000 feet; or 14 psi at 6,001–8,000 feet.
- Weighted-gauge canner: process pints for 20 minutes or quarts for 25 minutes at 10 psi from 0–1,000 feet or 15 psi above 1,000 feet.
- When processing ends, turn off the heat and let the canner depressurize naturally. Do not force cooling. Follow the canner manufacturer's opening directions, then lift jars upright and cool undisturbed for 12–24 hours before checking seals.

About this recipe
A seasoned tomato sauce with chiles and onions, processed as a low-acid mixture in a pressure canner.
Before you begin
Hot pack only. Use 1-inch headspace. Select the processing time for jar size and the pressure for your gauge and altitude.
Altitude/pressure schedule
| Dial-gauge elevation | Pressure | Pints | Quarts |

| 6,001–8,000 ft | 14 psi | 20 min | 25 min |
| Weighted-gauge elevation | Pressure | Pints | Quarts |
|---|---|---|---|
| 0–1,000 ft | 10 psi | 20 min | 25 min |

FAQ
Can this be water-bath canned? No. Use the pressure-canning process specified by the tested source.
Recipe context and comparison
Unlike acidified salsa recipes, this tomato-and-vegetable sauce uses pressure processing and allows both pint and quart jars.
Troubleshooting
If pressure drops below the target, bring the canner back to pressure and restart the full processing time. Let the canner depressurize naturally.
