["* Prepare the sauce first.", "The yellowfin tuna should be cut into 2 thick rectangular pieces, approximately 1""x1""x2"".

Make sure the flame is low because nori burns very easily. This is done to make it more flavorful and to make it a little easier to manipulate.", "Cut the nori to about the same width as your tuna. Align one edge of the tuna with the nori, leaving half of the tuna off the edge of the nori. this will mean that as you wrap, the nori will meet up in the middle of one side, reducing the wrist that it comes unstuck during the cooking process.", "Simple roll the tuna in the seaweed and trim off the excess with a pair of sheers. Repeat with the other piece of tuna.", "In the mean time, heat the coconut oil in a small skillet over a medium heat.", "Prepare 3 bowls; one with a blend of coconut flour and sea salt, one with shredded coconut and another with a beaten egg white.", "Brush the nori wrapped tuna lightly with egg white.", "Dredge the tuna in coconut flour and dip it again in the egg white. This will form the ""glue"" that will bind the shredded coconut.", "Roll the tuna in shredded coconut then roll it again in egg white.", "Finally pass it one last time in the shredded coconut.", "Using a pair of tongs, place the tuna on the hot skillet. Watch it carefully and sear for about 20-30 seconds each side or until golden brown, grasping the tuna from the long ends so as not to disrupt the crust.", "When each piece has finished cooking, remove it from the pan and plate immediately, cutting on the diagonal adds flair.", "In a small saucepan combine the orange juice, lime juice, mango, chili, sugar and ginger. Bring the mixture to a boil over a medium flame, then lower the flame and allow the liquid to simmer until it has reduced by half the volume.", "Allow the liquid to cool and then strain. Wisk in the vinegar and the grape seed oil to create the emulsion. Adjust the flavor with salt and pepper, to suite your taste.", "Drizzle over the seared coconut nori crusted tuna or serve in a separate dish for dipping."]
