I worked at KFC. The bread is ready-made. The chicken legs (hamburger legs) are also semi-finished products. They are thawed and put into the marinating machine for marinating. As for the marinade (called ETC marinade, why is it called that? I don’t know) someone else also prepared it for bagging. We poured it into the marinade for chicken drumsticks with a good ratio of water and marinated it. The crispy chicken burger bread was ready-made. As for the chicken patties (called vegetable chicken patties), they were ten to one. The bags are all semi-finished products and their ingredients are kept secret~ we don’t know.
