Wash the wings and wipe off the water. Make cuts to underside (opposite side from the skin side).
Heat a pan with a generous amount of sesame oil and fry from the skin side facing down. Don't turn it until it has a golden brown color.
Turn over when the color is golden brown and cooked through thoroughly. Check if it is cooked through or not, peeking in the cuts you made in Step 1.
When the chicken is cooked through, wipe off the excess oil in the pan with a paper towel.
Add the seasoning ingredients, soy sauce, sake, mirin and sugar you mixed in advance to the pan and coat the wings well in low heat.
When the sweet and salty sauce has coated the wings well, then it's done! Sprinkle white sesame seeds if you like and enjoy.
Story Behind this Recipe
I used our family's secret sweet and salty sauce (the amount of ingredients, soy sauce : sake : mirin : sugar = 1 : 1 : 1 : 1/2 ratio plus a drizzle of sesame oil) and arranged it to make this recipe.
-Washing the wings before cooking removes the smell and make the chicken wings more delicious. -The wings would be delicious if you fry them in medium heat and crisp the skin. -The sweet and salty sauce easily gets burnt so flip the wings and cook in low heat while coating the wings with the sauce.
