# What You Need:
→ Tuna
01 - 2 sushi-grade tuna steaks, 6 oz each, about 1 inch thick
02 - 1 tablespoon soy sauce
03 - 1 teaspoon sesame oil
04 - Salt and freshly ground black pepper to taste
→ Crust
05 - 1/2 cup black sesame seeds, toasted
06 - 1/4 cup white sesame seeds, toasted (optional)
→ Wasabi Mayo
07 - 1/4 cup mayonnaise
08 - 1 to 2 teaspoons wasabi paste
09 - 1 teaspoon rice vinegar
10 - 1 teaspoon fresh lemon juice
→ Garnish
11 - Thinly sliced scallions

# How-To Steps:
01 - Pat tuna steaks dry with paper towels. Brush all sides with soy sauce and sesame oil. Season lightly with salt and pepper.
02 - Spread black and white sesame seeds on a shallow plate. Press each tuna steak into the seeds, coating all sides evenly and firmly.
03 - Heat a non-stick skillet or cast-iron pan over high heat until very hot. Add a small amount of neutral oil.
04 - Sear tuna steaks for 30 to 45 seconds per side, just until the sesame crust is golden and the interior remains rare. Remove from pan and rest briefly on a clean plate.
05 - In a small bowl, whisk together mayonnaise, wasabi paste, rice vinegar, and lemon juice until smooth. Adjust wasabi intensity to your preference.
06 - Slice tuna steaks against the grain into 1/2-inch thick pieces using a sharp knife.
07 - Arrange tuna slices on serving plates. Drizzle with wasabi mayonnaise and garnish with scallions, pickled ginger, and lemon wedges.
