Winter Mushrooms and Cabbage

• Winter mushrooms (doeng gwu) preferably small whole ones, soaked
• Choi sum, washed
• Ginger
• Oyster sauce

Parboil the cabbage until just tender; while still bright green, drain; arrange on a serving dish. Stir-fry the mushrooms in oil with a slice of ginger; add the liquid in which the mushrooms soaked, and water or chicken stock to cover the mushrooms about three-quarters. Cover and simmer 4 to 5 minutes. Season with oyster sauce, thicken with cornstarch if necessary, and pour mushrooms — cum sauc
