How to make Unagi-Style Tulingan Maki Sushi:

• After frying the tulingan (skipjack tuna), remove the whole fillet from the bones, then cut it in half lengthwise. Set aside.
• Make teriyaki sauce by combining all the ingredients listen above and let it simmer for about 2 minutes. Add the slurry and let it simmer for around 1 minute to thicken.
• Place the fried tulingan fillet in the teriyaki sauce, marinate for 15 minutes.
• Combine the mirin and sugar in the newly cooked rice. Mix well, then season to taste with salt and pepper. Cover it with cling wrap and set aside.
• If you don't have a sushi rolling mat, you can use a cling wrap instead. Place a sheet of cling wrap over your chopping board.
• The wrap should be bigger than your nori sheet, rough side up, then place a a sheet of nori on the cling wrap and place a thin layer of rice over the nori, leaving 1 inch space from the top.
• Place the sliced marinated tulingan fillet over the rice, then roll it using the cling wrap to help you roll it perfectly.
• Take out the plastic wrap and cut it into 8, using a wet knife every slice to prevent the rice from sticking to the knife.
• Serve with soy sauce and wasabi.
