A soy egg is a type of egg in Chinese cuisine, Japanese cuisine, and Mauritian cuisine which is boiled, peeled, and then cooked in a mixture of soy sauce, sugar, water, and other optional herbs and spices. Other ingredients such as meat, vegetables and tofu can be cooked in the same red cooking method, resulting in dishes generally referred to as lou mei. Soy eggs can be made from chicken, duck, and quail eggs.
