# Instructions:
01 - Pat tuna steaks dry with paper towels. Brush all sides with soy sauce and sesame oil. Season lightly with salt and pepper.

04 - Sear tuna steaks for 30 to 45 seconds per side until the sesame crust turns golden and the interior remains rare. Remove from pan and rest briefly.
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 seared tuna steaks against the grain into 1/2-inch thick slices.
