Soy-Braised Frozen Tofu - cooking recipe

Ingredients

1 (14 ounce) package regular tofu
2 2 cups vegetable stock or 2 cups dashi
1/4 cup dark soy sauce
1/4 cup sake or 1/4 cup rice wine
1/4 cup mirin or 2 tablespoons sugar
sliced green onion, for garnish

Preparation

Wrap tofu in cheesecloth and freeze overnight (or up to 2 weeks). The tofu will turn yellow and leathery.
Run hot tap water over the frozen block until the cheesecloth can be removed. Put tofu in a large pot of boiling water for 15 minutes, until it softens.
Bring stock, soy sauce, sake and mirin to a boil in a medium pot. Cut tofu into 1\" cubes and add to simmering liquids. Simmer 25 minutes over medium-low heat, until the tofu has absorbed all but 1 tbsp of liquid. Sprinkle with sliced green onions before serving.
