Mongolian Hot Pot - cooking recipe

Ingredients

1/4 cup sherry wine or 1/4 cup white grape juice
2 1/2 tablespoons gingerroot, finely grated
2 tablespoons soy sauce
2 tablespoons peanut oil
1 tablespoon brown sugar
1 tablespoon cornstarch
2 large garlic cloves, crushed
1/2 teaspoon red pepper flakes
12 ounces flank steaks or 12 ounces sirloin steaks, very thinly sliced across the grain and cut into 1 1/2-inch lengths
1 lb bok choy, thinly sliced crosswise
3 1/2 ounces fresh shiitake mushrooms, wiped, stems removed, and thinly sliced
4 large scallions, thinly sliced
2 medium carrots, peeled and cut into 1/4 inch slices
4 cups beef stock (I would use more...at least a cup more)
2 cups water
1/3 cup hoisin sauce
4 ounces soba noodles
chinese hot pepper oil, to taste

Preparation

Combine the sherry, ginger, soy sauce, 1 tbsp oil, brown sugar, corn starch, garlic, red pepper flakes, and beef in a resealable plastic bag and seal. Turn several times to coat and marinate 30 minutes at room temperature, or refrigerate for up to 24 hours.
Heat a large wok or pot over high heat. Add 1 tsp oil. Lift the beef from the marinade with a slotted spoon, reserving the marinade. Quickly stir-fry the beef until lightly browned on both sides, about 1-2 minutes. Remove from the pan and set aside.
Add the remaining oil and stir-fry the bok choy, shitakes, scallions, and carrots for 1-2 minutes. Add the reserved marinade, stock, water, and hoison sauce. Bring to a boil. Stir in the noodles and simmer until tender, about 8-10 minutes. Return the beef to the wok or pot, cooking just long enough for the beef to heat through. Finish with a few drops of Chinese hot pepper oil. Do not let it sit before serving, or the noodles with absorb the liquid and swell!
