Japanese Cold Tofu
Special Soy Dressing (Hiyayakko)
A refreshing summer appetizer of chilled silken tofu dressed in a savory umami-rich bonito soy sauce and topped with seaweed and scallions.
Hiyayakko is a classic Japanese summer comfort dish designed to beat the heat with minimal cooking. It relies on the pristine, velvety texture of chilled silken tofu contrasted with a savory, aromatic dashi-infused soy dressing. Topped with smoky bonito flakes and crisp nori shreds, it offers a clean and delicate flavor profile that refreshes the palate instantly.
Ingredients
- 1 block silken tofu
- 60 ml water
- 3 tbsp reduced-salt light soy sauce
- 1 small handful bonito flakes
- 1 pinch seaweed shreds
- to taste chopped green onion
Instructions
- 1Boil the water

Begin by pouring 60 milliliters of clean water into a small pot on the stove. Turn on the heat and bring the water to a gentle boil to form the base of the sauce.
Tip: Measuring the water precisely ensures that the sauce has the right concentration and doesnt become too diluted. - 2Add bonito flakes

Once the water is boiling, add a small handful of bonito flakes into the pot. This quickly infuses the water with a rich, savory umami flavor.
Tip: Bonito flakes steep very fast; they only need a brief moment in the boiling water to release their full aroma. - 3Season the sauce

Add 3 tablespoons of reduced-salt light soy sauce into the simmering bonito broth. Stir gently to combine the ingredients into a fragrant, savory dressing.
Tip: Using reduced-salt soy sauce keeps the dressing light and refreshing, perfectly complementing the delicate flavor of the tofu. - 4Stir the sauce mixture

Stir the water, bonito flakes, and reduced-salt light soy sauce together in the pot using a spoon until the ingredients are fully incorporated and the liquid is evenly mixed.
Tip: Stir gently to ensure the soy sauce and bonito flavor blend completely before pouring it out. - 5Cool the sauce

Carefully pour the prepared sauce mixture from the pot into a small glass bowl. Set it aside to cool down completely before using it.
Tip: Letting the sauce cool is essential; pouring hot sauce over cold tofu would compromise its refreshing texture. - 6Unmold the Tofu

Carefully take a whole block of white silken tofu out of its packaging and place it onto a wooden cutting board.
Tip: Handle the delicate silken tofu gently to prevent it from breaking apart prematurely. - 7Slice the Tofu

Use a sharp kitchen knife to cut the block of silken tofu into smaller, delicate pieces.
Tip: Wipe the blade with a clean wet towel between cuts for clean edges. - 8Plate the Tofu

Carefully arrange the cut tofu pieces in neat order onto a patterned green serving plate using gloved hands.
Tip: Leave a small space between pieces if desired for better sauce coverage. - 9Pour the Sauce

Drizzle the cooled soy sauce mixture evenly over the arranged tofu pieces on the plate using a wooden spoon.
Tip: Make sure the sauce is fully cooled so it doesnt overly heat the cold tofu. - 10Garnish the Dish

Use chopsticks to delicately garnish the tofu pieces with dry bonito flakes and seaweed shreds.
Tip: Sprinkle the toppings evenly just before serving to keep the bonito flakes moving and textured.
