Step 1

If making salsa verde, blend tomatillos, avocado, onion, garlic, chile, cilantro, and 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt in a blender on medium-low speed until salsa is smooth. Taste and season with more salt if needed. (Do not blend on higher than medium speed or your salsa will be airy and taste like a smoothie.)

Step 2

If making salsa roja, blend tomatoes, onion, garlic, chile, cilantro, 1 Tbsp. lime juice, and 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt in a blender on medium-low speed until salsa is smooth. Taste and season with more salt and lime juice if needed.

Step 3

Do ahead: Salsa can be made 2 days ahead. Transfer to an airtight container; cover and chill.
