Sara Udon (Crispy Noodles with Seafood Thick Sauce)
Crisp fried thin noodles are buried under a hot, glossy sauce of pork, shrimp, squid, and vegetables thickened with potato starch. Chen Pingshun of Shikairo created it in 1899 as a soupless version of champon. Nagasaki still distinguishes the original thick-noodle style from the thin, crunchy style most people eat today, and this recipe follows the latter with store-bought fried noodles. Kamaboko, bean sprouts, and shiitake are added late so the sprouts keep their snap. Where the sauce soaks in, the noodles soften, and the rest stays crunchy.
