salsa recipe
Ha Ha Ha - every batch is different ! - I am not a purist.
During garden season, it is whatever I pick that is ripe, and grind it up together in the food processor.
But if I am shopping at the produce store, it is usually tomatoes (including tomatillos), peppers (multiple species sweet and hot), onions (including garlic and scallions), and various incidentals such as fresh herbs and dry spices including salt, pepper, cumin, and whatever. Tomatillos are cut into slices and roasted until they sweat and start to brown, but everything else is raw.
