I've always loved wasabi with tuna, but usually the wasabi overpowers such a delicate fish. When this recipe came to me through a friend, who doesn't recall its origins, I finally found the perfect marriage of flavors. I can't make this often enough!
- Drizzle sesame oil on both sides of each tuna steaks. Season with salt and pepper.
- Combine remaining ingredients in a small sauce pan. Heat over low heat until butter is melted, stirring constantly to mix and prevent scorching.
- While sauce is heating, heat a heavy frying pan on another burner with high heat. Place tuna in pan and sear until crispy and brown. Turn and sear on the other side.
- Note: Tuna steak fans who like their tuna on the rare side (like me) will usually find 2 minutes searing time is ample. Folks who like their tuna steaks more well-done (like my DH) may want to sear their tuna for 4-5 minutes per side.
