Chili pequin, bird peppers, the small wild ones go by many names. We use 14 with a cup and a half of roasted tomatoes, a half cup of diced red onion some fresh basil and four or five large roasted garlic toes. I have been picking them every day as they turn red. The small bowl was from yesterday minus 14. The others drying are the excess.

As mentioned, they go in everything we cook these days. They have quite a few interesting stories if you google them. Thomas Jefferson was able to grow them, so they should grow anywhere. Finding them wild is probably limited to Southwest US and northern Mexico.

Combine
Original recipe calls for 1/3 cup white onions, cilantro and 12 peppers. You can use a can of diced tomatoes and whatever as long as you have the chiltepin peppers, it will be okay. I've made this at least three times a week for maybe eight weeks; it varies, but this is how I made it this morning. Two heaping tablespoons with two eggs, two strips of bacon and some roasted potatoes makes a mean breakfast taco...d8)
Edit again to 18 chilis. From 12 to 18 in two weeks. Maybe 20 next time... still making salsa three times a week. Kids demand it.
