Soak the chile peppers overnight or boil until soft (about 30 min to an hour) in water (just enough water to cover the peppers).
De-stem the peppers
In a high speed blender, add the de-stemmed chile peppers and the rest of the ingredients.
Blend until smooth.
freeze in ice cube trays and/or store in fridge (though I don't know what the CDC would say, I store it for weeks) and use a couple tablespoons at a time in recipes.
Enjoy!
