Niku Udon (Japanese Thick Noodles in Dashi Broth with Braised Beef)
Thin shabu-shabu beef and onion, glazed in soy sauce, mirin, and sugar, sit on top of thick udon in clear dashi, giving the bowl a sweet, savory topping over a light broth. The beef is cooked in a separate pan rather than in the soup, which keeps its glossy finish and stops the broth from turning murky. It needs only about 2 minutes once the seasoning is added, at the point where half the red has gone, or it toughens. A little dashi is held back at the start to soften the broth if it tastes too salty. Rinsing the boiled noodles with hot water clears off their surface starch so the soup stays clean. Sliced scallions finish the bowl with a fresh edge.
