This is gently simmered tofu topped with a stir together sauce, commonly called banchan. It would make a great vegetarian course served with rice.You will want to eat the sauce on everything! Adapted from Gourmet magazine(March 2009).
Carefully rinse the tofu, then cover with cold water in a medium saucepan. Bring to a simmer over medium-high heat, then keep warm, covered, over very low heat.
Meanwhile, mince and mash garlic to a paste with a pinch of salt. Stir together with remaining ingredients (except tofu).
Just before serving, carefully lift tofu from saucepan with a large spatula and drain on paper towels. Gently pat dry, then move to a small plate. Spoon some sauce over tofu and serve warm. Serve remaining sauce on the side.
Sauce can be made 1 day ahead and chilled. Bring to room temperature before using.
