Ingredients
Scale
1 pound sushi-grade Ahi tuna loin
1/4 cup white sesame seeds
1/4 cup black sesame seeds
1 tablespoon neutral oil (like canola or grapeseed)
For the Ponzu Sauce:
1/4 cup soy sauce (or tamari for gluten-free)
2 tablespoons fresh lemon or lime juice
1 tablespoon rice vinegar
1 teaspoon grated fresh ginger
1 teaspoon sugar
Instructions
Prepare the sesame crust: Spread the white and black sesame seeds on a shallow plate, mixing them together.
Prepare the tuna: Pat the tuna loin completely dry with paper towels. This helps achieve a good sear.
Coat the tuna: Lightly brush the entire surface of the tuna loin with a thin layer of neutral oil. Roll the oiled tuna firmly in the mixed sesame seeds until all sides are evenly coated.
Sear the tuna: Heat a heavy-bottomed skillet (cast iron works well) over high heat until very hot. Add the remaining oil. Carefully place the sesame-crusted tuna in the hot pan. Sear for 30 to 45 seconds per side, turning carefully with tongs, until the sesame seeds are golden brown and the tuna is seared on the outside but remains raw in the center.
Chill the tuna: Immediately remove the seared tuna and place it on a plate. Cover loosely with plastic wrap and place it in the refrigerator to cool for 5 minutes. This stops the cooking process.
Make the dipping sauce: While the tuna chills, whisk together the soy sauce, lemon/lime juice, rice vinegar, grated ginger, and sugar in a small bowl until the sugar dissolves. This is your Ponzu Sauce Recipe.
Slice the tuna: Using a very sharp knife, slice the chilled tuna against the grain into thin, uniform pieces (about 1/4 inch thick).
Serve: Arrange the slices on a platter. Serve immediately with the Ponzu dipping sauce on the side. This makes a great Ahi Tuna Appetizer or Tataki Bowl base.
Notes
Use only the freshest, sushi-grade tuna available for safe consumption.
For an extra layer of flavor, you can add a dash of toasted sesame oil to the Ponzu sauce.
If you prefer a spicier flavor, add a pinch of red pepper flakes to the dipping sauce.
