Kimchi Stir-Fried Udon (Pork Belly Kimchi Wok-Fried Noodles)
Thin-sliced pork belly fried until golden renders the fat that everything else cooks in. Onion, scallion and kimchi go into that fat, and the kimchi keeps frying until its juice has nearly gone, concentrating flavor and keeping the noodles from turning soggy. Older, more fermented kimchi gives a deeper sour note to the finished udon.
