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.

Dried jalapeno pieces can be used fresh from the package in soups, braises and other recipes that will rehydrate them during the cooking process. Alternatively, they can be rehydrated prior to use (
How to Rehydrate Dried Chiles) or ground into jalapeno chili powder (
How to Grind Your Own Chile Powder).
Jalapeno chilies work especially well paired with cheeses, citrus juices (especially lemon) and onions.
