Animal butter is extracted from animal fat, which has a strong milk flavor and rich taste. It can provide more flavor and taste for steak during cooking and make it more delicious. Animal butter also has high thermal stability and can withstand high temperature cooking without gelatinization or deterioration. In contrast, vegetable butter is made of vegetable oil, but its taste and taste are relatively light. Vegetable butter is easy to gelatinize at high temperature, so it is not suitable for cooking steak at high temperature. Therefore, considering comprehensively, animal butter is more suitable for frying steak.
