This silken tofu, draped in a tangy, savory, chile-sweet gochujang sauce, is a warm weather epiphany: No cooking whatsoever. The sauce is essentially a chojang, a portmanteau of the Korean words for vinegar, cho, and for gochujang, the fiery fermented red chile paste, one of South Korea’s most delicious exports. Often served alongside salted boiled broccoli with sesame, this sauce is also excellent with tofu or on cold, crisp lettuce or hydrating cucumber and pepper. Make a double batch of the sauce, if you like, to keep in the fridge for last-minute crisper-drawer raids. Enjoy this on its own or with a bowl of cooked rice.
