Ingredients:

  • 4 Ahi Tuna (Sushi-Grade) Steaks (approx. 6 oz each)
  • 1 Tbsp Coarse Sea Salt
  • 1 Tbsp Freshly Cracked Black Pepper
  • 1 Tbsp Toasted Sesame Oil
  • 1/4 cup White Sesame Seeds
  • 1/4 cup Black Sesame Seeds
  • 2 Tbsp High-Heat Neutral Oil (e.g., Avocado or Grapeseed)
  • 1/4 cup Low-Sodium Soy Sauce (or Tamari)
  • 2 Tbps Rice Vinegar (unseasoned)
  • 1 Tbsp Fresh Ginger, finely grated
  • 1 clove Garlic, minced
  • 1 tsp Honey or Maple Syrup
  • 1/2 tsp Squeeze of lime or lemon juice
  • 2 strands Spring Onion (Scallions), finely sliced (Optional Garnish)
  • 1 Tbsp Fresh Coriander (Cilantro), chopped (Optional Garnish)

Instructions:

  1. Prepare the Tuna Steaks: Carefully blot all four tuna steaks very dry using kitchen paper. Evenly sprinkle the tuna steaks with salt and pepper.
  2. Coating and Dredging: Brush the steaks lightly all over with sesame oil. Combine the black and white sesame seeds in a shallow dish. Press each steak firmly into the sesame mixture on all sides, ensuring a thick, even crust. Place on a clean plate and chill for 10 minutes.
  3. Prepare the Ginger-Soy Dressing: Whisk together the soy sauce/Tamari, rice vinegar, grated ginger, minced garlic, honey/maple syrup, and lime/lemon juice in a small bowl. Taste test and set aside.
  4. The Searing Process: Place a heavy-bottomed skillet (cast iron is ideal) over high heat. Add the high-heat neutral oil and let the pan get smoking hot (about 2–3 minutes).
  5. Sear: Carefully place the tuna steaks into the hot pan. Sear for exactly 60–90 seconds per side for a classic rare centre. Use tongs to sear all four thin edges of the steaks for about 30 seconds each, just to set the crust.
  6. Rest and Slice: Immediately remove the tuna from the pan and place it on a clean chopping board. Allow the tuna to rest for only 2–3 minutes. Using a sharp knife, slice the steaks against the grain into 1/4 inch thick slices.
  7. Serve: Arrange the sliced tuna attractively on plates. Drizzle the Ginger-Soy Dressing generously over the slices and sprinkle with sliced spring onion and chopped coriander (if using).
