Q: I've been looking at a number of kim chi recipes and they all call for 'Korean chili powder'. My visit to the local Asian grocer only yielded 'Asian' chili powder and other nondescript chili powders.Is there a particular chili powder that is Korean? Can I simply use cayenne pepper or crushed red pepper flakes?
A:
How does Korean chili powder differ from "US" chili powder?
