Gochujang, a Korean fermented chile paste, enlivens a straightforward dinner of roast chicken and vegetables with a salty, spicy and umami-rich layer of flavor Freshly grated ginger, sliced scallions and quick-pickled radishes elevate the flavor even further This recipe calls for a wintry mix of squash and turnips, but equal amounts of root vegetables like carrots, potatoes and beets, or lighter vegetables like cauliflower, brussels sprouts or broccoli will work well too.
