Salami is a type of cured sausage made from fermented and/or air-dried meat. Traditionally, salami was made from pork, but nowadays it can be made with all manner of meat or game, including beef, lamb, duck, venison, and even horse meat. The meat is blended with fat and then mixed with herbs and seasonings, such as salt, garlic, or vinegar. The meat mixture may also have a small amount of preservatives included to provide color and to prevent bacterial growth. The mixture is then stuffed into an elongated casing made from cleaned animal intestines and left to ferment and dry for days, months, or even years. Salami can be stored at room temperature for up to 45 days once cut. There are many different types of salami, with Italy alone boasting of well over 150 different types.
