The essence of teriyaki sauce is to caramelize sugar. In the original recipes, the Japanese use mirin, a sweet rice wine. It is not easy to find it here, so they often use honey as a substitute.
Grate the ginger and garlic and mix everything for the sauce.
Chop the chicken, add salt and pepper. Heat the oil and fry until Golden brown.
Pour in the sauce and simmer until the chicken is tender and the sauce thickens, about 3-5 minutes.
Thickening, in this case, is a sign of the same caramelization. You can serve, for example, with rice. Pour the sauce on top.
