Ingredients
For the Tofu
- 2 packages (14 oz / 400 g each) silken tofu, well chilled
- 2 cups ice cubes, for serving
- 4 paper towels, for draining
For the Soy-Dashi Sauce
- 3 tablespoons soy sauce
- 2 tablespoons mirin
- 1 tablespoon dashi stock (or 1/2 teaspoon dashi powder dissolved in 1 tablespoon water)
- 1 teaspoon rice vinegar
- 1/2 teaspoon sugar
For the Toppings
- 4 green onions, finely sliced on the bias
- 1 tablespoon freshly grated ginger
- 1/4 cup bonito flakes (katsuobushi)
- 1 tablespoon toasted sesame seeds
- 1 sheet nori, thinly shredded (optional)
Directions
- Remove the silken tofu blocks from their packaging and place them on a layer of paper towels; let drain gently for 10 minutes to remove excess water.
- Carefully cut each block of tofu into 4 even squares using a thin knife dipped in water, wiping the blade clean between cuts.
- Arrange a bed of ice cubes on a platter or individual chilled plates and place the tofu squares on top.
- In a small bowl, whisk together the soy sauce, mirin, dashi stock, rice vinegar, and sugar until the sugar dissolves.
- Spoon about 1 teaspoon of the sauce over each tofu square, then top each with a generous pinch of green onions, grated ginger, and bonito flakes.
- Sprinkle the tofu with toasted sesame seeds and shredded nori, if using, and serve immediately.
- Pass the remaining sauce on the side so each diner can adjust the seasoning to taste.
Cook’s Notes
- Choose the freshest silken tofu you can find; it should be smooth, jiggly, and free of any sour aroma.
- Chill the tofu in the refrigerator for at least 1 hour before serving for the best cool, refreshing texture.
- Bonito flakes are traditional but can be omitted for a vegetarian version; a pinch of shiso leaf makes a great substitute.
- Use a very thin knife (lightly wet) to cut the tofu cleanly without tearing its delicate surface.
- Serve the tofu immediately after dressing to keep the texture firm and prevent it from becoming watery.
