If your tuna steaks were frozen, defrost them first. Gently dab them with paper towels to soak up any extra moisture.
02 -
Grab a bowl and toss in the Key lime juice, soy sauce, sesame oil, and ginger slices. Give it a good stir till everything's blended together nicely.
03 -
Put the tuna steaks in either a sealable bag or a non-reactive container. Pour the marinade over, making sure all sides get covered. Seal it up or cover and pop it in the fridge for at least half an hour.
04 -
Warm up your grill to high, or place a skillet over a medium-high stovetop flame. Brush oil onto the grill or pan to keep the tuna from sticking later.
05 -
Take your marinated steaks out of the fridge. Let them sit for around 10 minutes till they adjust to room temperature, then sprinkle both sides generously with the pepper.
06 -
Place the steaks on the grill or pan once it's hot enough. Cook each side for about 1-2 minutes if you're going for rare or medium-rare. Avoid overcooking to keep the lovely pink center intact.
07 -
Take the steaks off and let them rest a few moments. Grab a sharp knife and cut them into thin slices, going against the grain for the best results.
08 -
Lay the sliced tuna out on a platter. If you'd like, sprinkle on some extra ginger for garnish, and serve while warm.
