Tofu Umezu-zuke (Plum Vinegar Pickled Tofu)
Golden grilled slices of momen tofu soak for about a week in umezu, the salty, sour liquid that rises when plums are cured. The result pairs bright acidity and strong salt with a dense, almost creamy interior. This Kochi side dish is eaten in thin slices with drinks. For home use, the recipe calls for bottled food-grade umezu and tofu heated through before it goes into the refrigerator to cure.
