Ingredients

1/2 cup peanut or vegetable oil 

3 tablespoons crushed red-pepper flakes 

Preparation

Heat oil in a wok or skillet until hot, but not smoking. Carefully add pepper flakes, and remove from heat. Let stand until cooled completely. Transfer to a glass jar, and store, covered, in a cool place. If you wish, strain after several days, reserving liquid and flakes separately.
