Ankake Udon (あんかけうどん)

Ankake udon is winter food because it holds its warmth. Plain udon broth slips away quickly, as good broth should. Thicken it lightly, and it coats each noodle, carrying dashi, soy, mirin, and ginger with every bite. A small mercy, which is often the best kind.

People make the thickening sound delicate. It isn't. The one detail that decides it is the slurry: kuzu or potato starch mixed with cold water, stirred in slowly while the broth is moving. Add dry starch straight to hot broth and it clumps, because the outside seizes before the inside can disperse. Cold water gives it time to open evenly. That is the whole secret, not a ceremony.

Keep the broth clear and restrained. This is not a stew, and the starch is not there to hide anything. We build the flavor from dashi first, then season it with the two quiet hands of washoku, soy sauce and mirin. Grated ginger at the end wakes the bowl without shouting. Serve it hot, with room in the bowl, and let the shine of the broth tell you the meal is ready.
