In a bowl, soak the dried shiitake mushrooms in at least 1.5 cups of hot water and cover to let rehydrate. This should take 20-30 mins, with thicker mushrooms taking slightly longer.
6-8 dried shiitake mushrooms
Meanwhile, prepare the veggies, aromatics, and Chinese sausage. Slice the napa cabbage into 1/2 inch strips. Slice the baby bok choy in half vertically (or quarters if the bok choy is larger).
5-6 oz napa cabbage, 5-6 oz baby bok choy
Mince the garlic, ginger, and slice the scallions (separate the white and green parts).
4-5 cloves garlic, 1 inch knob of ginger, 2 stalks scallions
Slice the chinese sausages on a bias, to increase the surface area of each piece. When shiitake mushrooms are fully rehydrated, squeeze out the liquid, remove the tough stems, and slice them into strips. Set aside 3/4 cup of the mushroom liquid for cooking.
2 Chinese sausages
Mix all the seasoning ingredients together and set aside.
1 tbsp light soy sauce, 1 tsp dark soy sauce, 1 tbsp Shaoxing wine, 1/2 tbsp oyster sauce, 1 tsp sugar, 1/8 tsp white pepper
