Beer-based refers to products or dishes that incorporate beer as a primary ingredient. This can include a variety of foods, such as beer-battered fish or beer-infused sauces, where the flavors of the beer enhance the overall taste. The alcohol content often evaporates during cooking, leaving behind the rich flavors and aromas. In addition to food, beer-based beverages can also refer to cocktails or mixed drinks that use beer as a key component. Popular examples include beer margaritas or shandies, which combine beer with other ingredients for a refreshing twist. These creations highlight the versatility of beer in culinary applications.
