Ingredients:
Serves - 2-3; Preparation time - 15 mins; Cooking time - 20 mins
Adapted from Cooking light - way to cook vegetarian cookbook
Vegetable Stock - 2 cups
Water - 1-1/2 cups
Ginger - 1 tsp minced
Garlic - 1 tsp minced
White Mushroom - sliced thin - 1 cup (about 5-6)
Asparagus - sliced on a bias - 1 cup (about 7-8)
Extra Firm Tofu - 4 oz ~ 100 g - cut into cubes
Rice wine vinegar - 2 tbsp
Soy sauce, low sodium - 1/2 tbsp
Black Pepper, freshly ground - 1/2 tsp
Corn Starch - 1 tbsp
Water - 2 tbsp
Egg whites, lightly beaten - from 2 eggs
Scallions/Spring onion greens, a handful - chopped
Cilantro - chopped - a handful
Method:
Whisk together the vinegar, soy sauce and pepper in a small bowl. Mix 1 tbsp of corn starch with 2 tbsp of water in another small bowl. In a non-stick pan spray some oil and toss around the tofu until it crisps up ever so slightly. In a large pot mix the stock, water, ginger and garlic and bring it to a boil. Meanwhile saute the sliced mushrooms and asparagus one by one with very little oil, for about a minute each. When the soup boil, add the veggies and simmer for 5 minutes. Add the vinegar mixture and tofu. Simmer for another 5 minutes. Pour the corn starch mixture and mix well. Continue to simmer for another 3 minutes or until the soup thickens a little. Stirring continuously with a wooden spoon, pour the egg whites in a steady stream until tiny ribbons form. Remove from heat and garnish with cilantro and scallions. Serve hot.
Notes: The soup does not need salt because of the salt in the soy sauce and stock. But you may add salt for your taste.
