Storage: Store ancho chili peppers in an air-tight container in a cool, dark cupboard.
Shelf Life: Anchos will retain their flavor for at least a year, but likely much longer.

Ancho chilies are most often ground into chili powder for culinary use rather than being rehydrated. No traditional mole sauce is complete without ancho chilies, but they can also be used in salsas, sauces, soups, and even desserts.
