Step 1

In a pan, on low/medium heat, toast the chile ancho, new mexico or guajiilo and chile de arbol for a few minutes. Don't let them burn, just until they become aromatic and dry out a little more. Remove from heat and let them cool.

Step 2

In that same pan on low/medium heat, toast the coriander seeds, cumin seeds, oregano, peppercorns, cloves, cinnamon and anise until they become aromatic. Toast for about 5 minutes, stirring now and then.Remove from heat.

Step 3

Remove the stems and seeds from peppers. Tear the peppers into smaller pieces. In batches, grind all the toasted peppers and toasted spices to a fine powder, mix  all together.

Step 4

In a large bowl, combine the ground spice mix with remaining spices, ground pork and vinegar. Mix well until spices are distributed evenly. Cook a small portion of the chorizo to check for seasoning. Add seasoning to taste. Cover and refrigerate overnight. The flavors will improve imensely the longer the chorizo marinates in the spices. If not using right away, freeze in 1/2 portions using quart size freezer bags. Yields 8 to 10 servings.
