Aromatic Asian Broth with Water Chestnuts and Scallops

This subtle soup surprises. Its pale and polite appearance belies a big bouquet and hot kick. And although scallops and water chestnuts look similar, their textures are shockingly different. Serve as an appetizer for a light supper, followed by Buckwheat Noodles, Mizuna, and Radishes with Tart Tofu-Mizuna Dressing or Sesame Noodles with Radishes and Garden or Upland Cress.
