A sausage is mainly made of ground meat, often pork, beef, or poultry. It includes salt, spices, and sometimes fillers like grains. When we say sausage, we often mean loose meat for patties or casings. A “sausage” usually refers to an encased, cylindrical product. Sausages are typically in casings made from intestines or synthetic materials. Raw sausages can be pan-fried, broiled, or barbecued. Some are pre-cooked, and their casings might be removed. Making sausages is a traditional way to preserve food. Methods include curing, drying, smoking, and freezing. Some sausages can be stored without refrigeration. Most fresh ones need to be refrigerated or frozen. Sausages vary by region and country. Differences include meat types, flavours (like garlic or wine), and preparation methods. Nowadays, vegetarian and vegan sausages are increasingly popular, using plant-based ingredients.
