Tuna Preparation

Caramelized Onions

Garnishes

Spicy Ponzu Sauce

Method

Prepare the Tuna

  1. 1

    Coat the Tuna

    Season the Ahi tuna steaks with salt and black pepper. Press the sesame seeds onto both sides of the tuna steaks until well coated.

  2. 2

    Sear the Tuna

    In a skillet, heat olive oil over medium-high heat. Sear the tuna steaks for about 30 seconds on each side for rare, or longer if desired. Remove from heat and set aside.

Caramelize the Onions

Prepare the Spicy Ponzu

    In a bowl, combine soy sauce, rice vinegar, lime juice, Sriracha, and dashi stock. Stir well and adjust to taste.
