Mai Le Chicken was popularized in 1983. It is made of boneless chicken pieces wrapped in bread crumbs. These chicken pieces consist of chicken legs and chicken breasts, each accounting for 50%. It was invented by René Allen, a chef squeezed out by McDonald's. He is also the inventor of chicken mcnuggets sauce. Chicken mcnuggets are covered with a layer of batter, then a layer of bread crumbs, and finally a layer of egg milk powder paste. After pre-frying, it is quickly frozen to maintain its freshness and quality. Chicken mcnugget sauce can be divided into sweet and sour sauce and garlic sauce. Sweet and sour sauce is made of Japanese sauce and pure apricot meat, and garlic sauce is made of sugar, vinegar, pepper, salt and garlic.
