2. Remove stalks from mushrooms and discard. Soak mushroom heads for
20 to 30 minutes until soft, then steam with steaming seasoning
ingredients for 30 minutes. Remove and stir-fry with stir-frying
seasoning mixture until there is no liquid left. (If button
mushrooms are used, soaking and steaming is not necessary. Instead,
simmer mushrooms with 2 slices of ginger and 2 shallots for 1 minute.)
