Place the tofu in a shallow sauce pan and cover with cold water. Noe: I like to cut the block of tofu in half. Bring to a simmer over medium-high heat, then keep warm, covered, over very low heat for at least 20 minutes.
Meanwhile, mince and mash the garlic to a paste. Stir together with the remaining ingredients.
Just before serving, carefully lift the tofu from the saucepan with a large spatula and drain on a towel (or simply use a slotted spatula and skip the drying step). Transfer the block or blocks of tofu to a shallow bowl or bowls. Spoon the sauce over the tofu and serve warm.
