This recipe combines the bold flavors of sesame and wasabi with the freshness of tuna, creating a delightful dish perfect for summer grilling.
Mix the sesame seeds, wasabi powder, ground pepper, garlic powder, and salt in a bowl.
Toast the sesame seeds beforehand for an enhanced nutty flavor.
Rub the sesame-wasabi mixture evenly over the tuna steaks.
Press the mixture gently to ensure it adheres well to the tuna.
Preheat the grill to high heat.
Ensure the grill is clean and lightly oiled to prevent sticking.
Grill the tuna steaks for about 5 minutes on each side, or until cooked to your preference.
For medium-rare, aim for a slightly pink center.
Whisk together the wasabi powder, water, mayonnaise, sour cream, lemon juice, soy sauce, and scallions in a bowl.
Adjust the wasabi quantity to suit your spice preference.
Serve the grilled tuna steaks with the creamy lemon sauce on the side.
Garnish with extra scallions or sesame seeds for presentation.
