To make fried tofu, salt and press the tofu, dredge it in flour, add it to a pan coated with hot sesame oil, and pan-fry it until both sides are golden and crispy. The required ingredients include medium-firm tofu, salt, sesame oil, soy sauce and sake. You also need scallions, sugar and black vinegar.
Take the tofu out of its package, put it on a cutting board, and cut it into 1/2-inch slabs. Sprinkle both sides of each piece with salt. Place the bottom of a heavy casserole dish on top of the tofu, and then raise one end of the cutting board by placing a small object underneath it. Let the tofu drain for 15 minutes.
Lift the casserole dish off the tofu and set it aside. Dry the tofu slabs with paper towels and dredge them in white flour. Put a pan on the stove over medium heat, pour in 2 tablespoons sesame oil, and then add the tofu. If the oil begins to smoke, reduce the heat.
Pan-fry the tofu without moving it until the lower edges turn brown, and then turn the pieces over. Cook them for about six minutes, or until both sides are brown. Lift the tofu out of the pan, and transfer it to a serving plate.
Turn off the burner and wipe the pan with paper towels. Return it to the stove, and add 1 tablespoon of soy sauce, 1 tablespoon sake, 1 tablespoon white sugar and 1 tablespoon black vinegar. Stir until the sugar dissolves and the sauce thickens, and then pour the sauce over the tofu. Sprinkle with chopped scallions and serve immediately.
