Main Ingredients

Ponzu Sauce

Garnish

Method

Preparation of Ponzu Sauce

  1. 1

    Make the Ponzu Sauce

    In a bowl, combine soy sauce, yuzu juice, rice vinegar, mirin, and bonito flakes. Stir well to mix all the ingredients.

  2. 2

    Strain the Sauce

    Let the ponzu sauce sit for a few minutes, then strain it through a fine sieve to remove the bonito flakes.

  3. 3

    Add Aromatics

    Slice scallions thinly and add them to the ponzu sauce along with sesame oil. Mix well and set aside.

Cooking Romanesco Cauliflower

  1. 4

    Prepare the Romanesco

    Remove the leaves from the Romanesco cauliflower and cut it into florets.

  2. 5

    Blanch the Cauliflower

    Bring a pot of salted water to a boil. Add the Romanesco florets and blanch for about 2-3 minutes until tender but still vibrant in color. Drain and transfer to an ice bath to stop the cooking.

  3. 6

    Sauté the Cauliflower

    In a skillet, heat a little olive oil over medium heat. Add the blanched Romanesco and sauté for about 5 minutes. Season with salt and pepper to taste.

Cooking Bluefin Tuna

  1. 7

    Prepare the Tuna

    Pat the Bluefin tuna steaks dry with paper towels. Season both sides with salt and black pepper.

  2. 8

    Sear the Tuna

    Heat a non-stick skillet over high heat. Add a small amount of oil. Once hot, add the tuna steaks and sear for about 1-2 minutes on each side for medium-rare, adjusting the time based on your desired doneness.

  3. 9

    Rest the Tuna

    Remove the tuna from the skillet and let it rest for a couple of minutes before slicing.

Assembly

  1. 10

    Plate the Dish

    On a plate, arrange the sautéed Romanesco cauliflower. Place the sliced Bluefin tuna on top.

  2. 11

    Add Grapefruit

    Segment the grapefruit and scatter the segments over the tuna and cauliflower.

  3. 12

    Drizzle Ponzu

    Drizzle the ponzu sauce over the entire dish and finish with a sprinkle of microgreens.

  4. 13

    Serve

    Serve immediately with additional ponzu sauce on the side.
