Method
Prep jars
- Sterilize canning jars and lids in boiling water, then keep them hot until ready to fill. Use a visual cue: jars should look clear and steaming when you remove them.
Blend salsa
- Working in batches, pulse the tomatoes, onions, jalapenos, and garlic in a food processor to your desired smoothness. Stop when the mixture looks evenly blended with a consistent ruby-red color.
Simmer salsa
- Pour the blended mixture into a large Dutch oven with vinegar and salt, then stir to combine. Bring the pot to a boil, with active bubbling across the surface.
Cook to slightly thickened
- Reduce heat and simmer for 20-25 minutes until slightly thickened, stirring occasionally. Visual cue: the salsa should look a bit glossier and cling slightly to the spoon.
Jar hot salsa
- Ladle the hot salsa into sterilized jars, leaving 1/2 inch headspace, then wipe rims and seal with lids. Visual cue: headspace should be uniform and lids should sit flat with sealed edges.
Process in water bath
- Process sealed jars in a boiling water bath for 15 minutes. Visual cue: water should stay at a steady rolling boil during processing.
Cool and check seals
- Let jars cool completely, then check that lids have sealed properly. Visual cue: lids will be concave and won’t flex when pressed.
Notes
Pulse vegetables in batches for an even, smooth restaurant-style texture, and keep jars hot until filling to prevent temperature shock. Sealed jars store in a cool pantry up to 1 year. Freezing is not recommended for this recipe because texture can change after thawing. For a lower-sodium option, reduce salt slightly only if following safe canning guidance, since salt affects taste and recipe balance.
