Where China borders Mongolia in the colder north, the food reflects the terrain—it’s rustic and comforting, loaded with rich lamb and focused more on wheat-flour noodles and buns than the rice ubiquitous elsewhere. Thanks to a change in immigration patterns, Flushing has seen an increase in Northern Chinese restaurants like the seven-year-old Fu Run, whose owners are from Dongbei (what was once known as Manchuria). They call their justly celebrated dish the “Muslim lamb chop,” but it’s more like a half rack of ribs: A platter of bone-in, fatty meat is braised, then battered and deep-fried, the whole juicy slab blanketed with cumin seeds, chili powder and flakes, and black and white sesame seeds. Try it with a wonderfully greasy beef-stuffed pancake called a bing, and cold saladesque dishes like the bright, fresh “tiger vegetable” (shredded scallions, cilantro, chilies and tiny shrimp) or liang pi noodles, transparent mung-bean noodles listed as “green-bean sheet jelly” and tossed with chili oil, peanuts and crushed cucumbers.
