Blackened Tuna Sushi

Combine all herbs and spices and grind in grinder or chop finely with a knife creating a dry rub. Heat butter in frying pan until melted, then roll tuna in butter. Use a plate or flat dish and spread rub evenly then roll the tuna to cover all sides with rub.

Heat butter again, being careful not to burn. Sear tuna in butter for 5–7 seconds on each side. Remove and use a sharp knife to slice the tuna into ¼-inch thick slices and arrange on a plate or serving dish.

Serve immediately with soy sauce and wasabi. In Japanese tradition, pinch the wasabi with your thumb and two fingers to form a mini Mt. Fuji.
