Su-tofu (Chilled Pickled Tofu)

Halve the tofu lengthwise. More cut surface area lets water drain and flavor soak in faster.

Wrap the cut tofu in paper towels or a kitchen cloth.

Place the wrapped tofu in a microwave-safe container, uncovered, and microwave at 600W for 3 minutes.

Combine vinegar, yukari, sugar, kombu cha, and salt to make the marinade.

Let the microwaved tofu cool slightly, then transfer to a plastic bag.

Pour the marinade into the bag, press out the air, and seal.

Refrigerate overnight.

Cut into bite-size pieces.
