Ancho chile pods can be used instead of pasilla chile pods. You can also substitute 24 cardamom pods for the ground cardamom; just crush the pods and remove the seeds.
Olive oil may be used in place of avocado oil. Dried cilantro can be substituted for dried epazote. Use 6 teaspoons fresh oregano instead of dried if desired.
If you are not serving these right away, pour into shallow pans to cool quickly. The pans can be frozen and reheated gently--warmed in the oven and then kept warm on a steaming table over hot water. Warning: the bottom will burn if there is not enough liquid!
