Ingredients
Method
Cooking
- Bring a medium pot of water to a gentle boil. Add the tomatoes, guajillo chiles, peeled garlic, and quarter onion.
- Simmer until the tomatoes are very soft and the skins begin to split — about 8–10 minutes.
- Transfer the vegetables and roughly 1 cup of the cooking water to a blender. Purée until completely smooth.
- Return the blended sauce to the pot. Season with salt to taste and cook over low heat for 5 minutes, stirring occasionally.
Blending
- Use a slotted spoon to move hot ingredients from pot to blender to avoid carrying too much water.
- Pulse first, then blend on high for a smooth finish. For chunkier salsa, pulse just a few times.
Notes
For a smokier sauce, briefly roast the tomatoes and onion instead of boiling. If using canned tomatoes, fresh gives the best brightness. Store in the fridge for quick meals.
