Approx 1 oz of dried chiles
- Preheat oven to 250f.
- Remove and discard stems and seeds of chiles.
- Place chiles on a baking tray/sheet pan and bake for 10-15 minutes to dry them out further. They should be more brittle and less pliable.
- Remove from oven and cool. Working in batches if necessary, place extra-dried chiles into a grinder and pulse to a fine powder.
- Store in an airtight container and use as needed.
