1, poor practice. Roast sheep's head needs to be cooked first and then roasted, and can't be cooked at the same time, while sauce sheep's head needs to be stewed and marinated, and can be cooked at the same time.
2, the taste is different. Roasted sheep's head is tight and chewy, and the sauce sheep's head is soft. Roasted sheep's head is suitable for teenagers and adults, and sauced sheep's head is more suitable for the elderly and children with imperfect teeth.
