Ginger-Lemon Grass Broth with Nameko

Slippery and exotic, this glistening mushroom suggests oysters, scallops, and satiny sexual parts. Its tawny hue remains after cooking, as does its defined, neat form. Prepare this light course using a broth that is clear and brisk, based on mushrooms, on a vivid vegetable combination, or seafood and vegetables, or veal and mushrooms. Reserve for amateurs of delicacy and slurp.
