What are Sausages Made of?
Sausages are usually made of pork, but halal, kosher, vegetarian, and vegan varieties of sausages also exist. The oldest sausage - the blood sausage - was made from various parts of the pig's body, fillers, and animal blood. Today, some variation of blood sausage exists in almost every culture and other sausages of all kinds are found as well.
