This express recipe (thanks to Mi Kyum Kim) mimics the punch of kimchi, but in a flash, sans fermentation. The secret to its signature pungency is salted, fermented shrimp paste (you can find it at your local Korean or Asian grocery store). If Korean chili powder (gochugaru) proves hard to track down, experiment with crushed red pepper for a fresh, crispy, spicy side inspired by Korea’s most iconic condiment.
