Homemade chicken nuggets are held together by a combination of ingredients and cooking methods. First, you coat the chicken pieces in beaten eggs, which act as a binder, helping the breadcrumb mixture adhere to the surface of the chicken. This ensures that the coating stays intact during baking, resulting in crispy nuggets with a flavourful exterior. Additionally, the baking process itself plays a crucial role in holding the nuggets together. By baking them at a high temperature, the egg and breadcrumb coating cooks and sets, creating a firm outer layer while sealing in the moisture of the chicken inside. Overall, the combination of egg as a binder and baking as a cooking method work together to hold homemade chicken nuggets together, resulting in deliciously crispy and flavourful bites.
