Ingredients

  • 14 oz extra-firm tofu(pressed to remove surface water)
  • 2 pieces dried kombu sheets(about 4x4 inches each)
  • 1 tbsp shio koji
  • 1 tbsp sea salt(fine sea salt)
  • 1 tsp sugar
  • 1 tsp beet powder(optional, for vibrant hue and earthy depth)
  • 2 cups cooked sushi rice(seasoned lightly with rice vinegar)
  • 2 tbsp yuzu juice(fresh or bottled Japanese yuzu)
  • 2 tbsp passionfruit puree(unsweetened)
  • 1.5 tbsp tamari(or gluten-free soy sauce)
  • 1 tsp green yuzu kosho(Japanese chili paste)
  • 1 tbsp toasted sesame oil
  • 1 tsp mirin
  • 1 ripe avocado(sliced)
  • 0.5 cup English cucumber(shaved into thin ribbons)
  • 0.5 cup shelled edamame(blanched)
  • 2 radishes(thinly sliced)
  • 1 stalk scallion(thinly sliced)
  • 1 tbsp toasted white and black sesame seeds(for garnish)

Instructions

  1. 1

    Wrap 14 oz extra-firm tofu in paper towels and place a heavy skillet on top to gently press out excess moisture.

    5 min

    Tip: Don't press so hard that the tofu cracks; you just want to draw out free surface water.

  2. 2

    In a small bowl, combine 1 tbsp sea salt, 1 tsp sugar, 1 tsp beet powder, and 1 tbsp shio koji. Wipe 2 pieces dried kombu sheets with a damp towel to activate them. Slice the tofu into 1/2-inch thick slabs, rub all over with the cure mixture, and sandwich the tofu tightly between the kombu sheets. Wrap in plastic film and set aside to cure at room temperature.

    15 min

    Tip: The salt draws out water while the kombu infuses natural glutamates directly into the tofu.

  3. 3

    While the tofu cures, prepare the electric ponzu dressing. In a medium bowl, whisk together 2 tbsp yuzu juice, 2 tbsp passionfruit puree, 1.5 tbsp tamari, 1 tsp green yuzu kosho, 1 tbsp toasted sesame oil, and 1 tsp mirin until smooth.

    5 min

    Tip: Emulsifying the sesame oil with the citrus cuts the harsh top-note of the acid and creates a rich mouthfeel.

  4. 4

    Prep your bowl garnishes: thin slice 1 ripe avocado, peel 0.5 cup English cucumber into long ribbons, thinly slice 2 radishes, chop 1 stalk scallion, and measure 0.5 cup shelled edamame.

    7 min

    Tip: Keep the veggies crisp by placing them in an ice water bath if you like extra crunch.

  5. 5

    Unwrap the cured tofu. Wipe off the excess salt and cure paste with a damp paper towel. Slice the firm, velvety tofu on a slight diagonal into 1/4-inch sashimi-style strips.

    3 min

    Tip: Notice how the texture has transformed from crumbly to dense, buttery, and translucent.

  6. 6

    Divide 2 cups cooked sushi rice between two lunch bowls or portable containers. Arrange the cured tofu slices, avocado, cucumber ribbons, edamame, and radishes on top. Drizzle generously with the Yuzu-Passionfruit Ponzu and garnish with 1 stalk scallion and 1 tbsp toasted white and black sesame seeds.

    4 min

    Tip: If taking to work, pack the dressing in a separate small container and pour right before eating.

Chef's Notes

Why this works: Tofu is 85% water, which is why it often tastes bland and diluted. By applying a dry cure of salt, sugar, shio koji, and wrapping it in dried kombu kelp, we trigger osmotic pressure. Water rushes out, concentrating the soybean proteins into a texture strikingly similar to cured salmon or gravlax. Simultaneously, the kombu transfers free glutamic acid (pure umami) right into the protein matrix. balancing Acidity: Passionfruit and yuzu bring intense citric and malic acidity. If used alone, they'd strip your palate. By whisking them with toasted sesame oil and tamari, we create a fat-stabilized emulsion that coats the tongue first, letting the sharp fruit acidity hit as a brilliant burst rather than a sour bite. Perfect for packing ahead—this won't get soggy or smelly at your desk!
