Prep Grill: Set up the grill for direct grilling with lump charcoal and target 600 degrees Fahrenheit. If using a gas grill use the burners on high for the same target temperature.
Season Meat: Coat in olive oil and sprinkle tuna with salt and pepper.
Grill: Place tuna steaks over the direct heat. After 2-3 minutes, the sear will occur and the tuna will easily release from the grill grates and ready to flip. If the tuna is not easily releasing, let it continue cooking another 30 seconds.
Flip: Flip steaks and continue cooking over direct heat again for 2 – 3 minutes. Then remove. You’ll see that the center of the tuna is still pink, which is the goal.
Serve: Serve immediately with the soy ginger dipping sauce.
Dipping Sauce
Combine: In a small bowl combine all ingredients and whisk to incorporate. Place in 4 small individual dipping dishes if serving as a main course or one dish if doing for an appetizer.
Optional: Sprinkle some sesame seeds into the dipping sauce.
Notes
Chef's Tip: Use a micro plane to grate the both the ginger and the garlic. It makes for very fine texture when in the dipping sauce. Another great trick is to freeze unused fresh ginger. You can remove from the freezer and simply grate it again for the next recipe.
