Beer marinade is a flavorful mixture used to enhance the taste and tenderness of meats. It typically combines beer with ingredients like garlic, onions, herbs, and spices. The alcohol in the beer helps to break down proteins, making the meat more tender while infusing it with rich flavors. This marinade is versatile and can be used for various types of meat, including chicken, beef, and pork. The choice of beer, whether lager, stout, or ale, can significantly influence the final taste. Marinating for a few hours or overnight allows the flavors to penetrate deeply, resulting in a delicious dish.
