The spicy taste of many Korean foods - red pepper powder. Red Chili Pepperis made by drying Korean red chili peppers in the sun, de-seeding them and crushing them into flakes.
I love McCormick's Peppercorn Medley! It's the perfect blend of peppercorns: Black, White, Green & Pink, PLUS Coriander and Allspice. Really, you need to try it and you will probably like it! (Or maybe you'll LOVE IT, as I do!)
