Spicy Rub for Seared Tuna Steaks

2 tablespoons olive oil

2 tablespoons grated lemon zest

2 teaspoons ground coriander

1 ¼ teaspoons ground black pepper

1 ½ teaspoons ground ginger

1 teaspoon salt

½ teaspoon ground cinnamon

4 (5 ounce) tuna steaks, about 1 inch thick

1 tablespoon olive oil

Whisk 2 tablespoons olive oil, lemon zest, coriander, black pepper, ginger, salt, and cinnamon in a small bowl; rub tuna steaks with spice mixture.

Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Sear tuna in the hot oil until browned but still pink in the center, about 3 minutes on each side.
