If you have sensitive skin, put gloves on. Slice each chile in half and remove the stems and seeds. Rinse well in a colander or strainer.
Place the chilies, onion, garlic, cumin, coconut sugar, and broth in a sauce pan.
Bring to a boil, then turn off the heat, cover, and allow to steep for 30-60 minutes, or until the chilies are soft and pliable. (The flavor is best if you allow it to steep 1 hour)
Transfer to a blender and process until smooth. Set aside.
If not using immediately, store in an air-tight container in the refrigerator for up to 1 week.
Notes
* 12-15 dried chilies* (2-3 passillo, 2-3 ancho, 8-10 Guajillo) or Anaheim (depending on desired spice level)
