Buy dried chillies in whole form, chopped pieces (flakes) or powder. Make sure packaging is secure, as chillies are prone to insect infestation.
Store chillies in airtight containers in a cool, dark place such as a pantry. In extremely humid areas, keep chillies in the fridge.
Tips & Tricks:
Add dried whole chillies to slow-cooked dishes such as soups, stews and curries. Flakes and powder can be added to virtually any food where a little heat kick is desired. Using whole, dried Mexican chillies such as Pasilla, Mulato or Ancho, shred very finely with a very sharp knife, and pile a little "nest" of shreds on icecream.
