Hot-and-Sour Soup (Shoon Lat Tong)
Notes: Grace Young's parents make their own broth with chicken, water, and fresh ginger, but canned chicken broth simmered with fresh ginger works well too. If cloud ears and lily buds are unavailable, substitute 1 cup finely shredded cabbage and 1 cup thinly sliced mushrooms and skip step 1; add cabbage and mushrooms to broth in step 4. You can prepare the soup through step 4 up to 1 day ahead; cool, cover, and chill. Reheat, covered, over high heat, then continue with step 5.
