Ingredients

Scale
  • 6 pounds Roma or paste tomatoes
  • 4 jalapeno peppers, halved
  • 2 poblano peppers, halved
  • 1 large white or yellow onion, quartered
  • 6 garlic cloves, peeled
  • 1 cup bottled lemon juice or 5% acidity vinegar
  • 2 teaspoons salt
  • 1 teaspoon ground cumin (optional)
  • 1/2 teaspoon black pepper
  • 1/4 cup chopped fresh cilantro (optional)

Instructions

  1. Preheat oven to 425°F. Arrange tomatoes, jalapenos, poblanos, onion, and garlic on a large baking sheet.
  2. Roast for 20 to 25 minutes until vegetables are softened and lightly charred. Broil for 2 to 3 minutes for deeper char if desired.
  3. Remove vegetables from oven and allow to cool slightly. Peel excess tomato skins if preferred.
  4. Transfer roasted vegetables to a large pot. Blend using an immersion blender or food processor to desired consistency.
  5. Add bottled lemon juice or vinegar, salt, cumin, and black pepper. Bring mixture to a boil, then reduce heat and simmer for 10 to 15 minutes.
  6. Stir in chopped cilantro if using.
  7. Ladle hot salsa into sterilized pint jars, leaving 1/2 inch headspace. Remove air bubbles and wipe rims clean.
  8. Place lids on jars and tighten bands fingertip tight.
  9. Process jars in a boiling water bath for 15 minutes, adjusting for altitude as needed. Remove and cool undisturbed for 12 to 24 hours before storing.

Notes

  • Always use bottled lemon juice or 5% acidity vinegar to ensure safe canning.
  • Do not reduce the acid quantity, as proper pH is critical for safety.
  • Use paste tomatoes for thicker salsa with less liquid.
  • Remove pepper seeds and membranes for a milder salsa.
  • Properly sealed jars can be stored in a cool dark pantry for up to 12 months.
