Storage: Store granulated chilies, chile pieces, and chile flakes in air-tight containers in cool, dry cupboards.
Shelf Life: Dried chile pieces will maintain their full flavor for at least twelve months.

Pasilla negro chilies are a central ingredient in Mexican moles. In addition, these granules work well used in cream sauces or desserts to add mild heat & rich chile flavor.
They take less time to rehydrate than larger chile pieces or whole chiles, so dishes made with them don't need to cook as long. Alternatively, they can be rehydrated prior to use (How to Rehydrate Dried Chiles) or ground into chipotle chili powder (How to Grind Your Own Chile Powder).
