   6                    dried New Mexican chiles
   6                    chipotle peppers
   3                    pasilla negro peppers
   2                    mulato peppers
   6      tablespoons   cumin seed
   6      tablespoons   coriander seed
   1      tablespoon    whole cloves
   3      tablespoons   celery seed
   2      tablespoons   ground cayenne

Preparation:

1. Break up the New Mexico, chipotle, and mulato chiles. Toast the chiles in small batches on an ungreased skillet, or comal over medium heat until they >just begin to release their aroma. Do not let them darken or the may become bitter. 2. Toast the cumin, coriander, and cloves on an ungreased skillet, or comal over low heat until they release their fragrance and become lightly roasted, about three minutes. 3. Grind the toasted spices and celery seed (best to use a spice grinder). 4. Grind the chiles in a spice grinder or food processor. 5. Mix the ground chiles, spices, and ground cayenne. This recipe is an adaptation of one appearing in "New Southwestern Cooking" by Dille and Belsinger. Since I never have the chiles called for in the recipe, I invariably "wing it." The spices seem to be the important factor so substituting different chiles doesn't make a major difference in the finished product.
