Cut the chicken thighs into bite sized pieces.
Coat the chicken thighs potato starch and shake off excess.
Heat up your vegetable oil in a deep pan or your deep fat fryer. Once the oil is HOT (around 350 degrees) place the chicken in the hot oil and fry until golden brown. You may need to turn the chicken over, and it should take between 3-7 minutes depending on how large the pieces of chicken are. Please adjust the time accordingly so that chicken is cooked to a golden brown! Remove once cooked and drain on paper towels.
Meanwhile prepare your yurinchi sauce, by combining the yurinchi sauce ingredients (sugar, soy sauce, sesame oil, rice vinegar, and chili oil to your taste).
To serve, place a few iceberg lettuce leaves on your plate, top with the yurinchi friend chicken, and a few spoonfuls of the yurinchi sauce. Sprinkle loads of green onions on top and some Nanami Togarashi for the finishing touch!
