Salami originates from Italy and has been produced there for centuries. The word "Salami" comes from the Italian word "salare," which means "to salt." Originally, salami was a method of preserving meat through salting, fermenting, and air drying.

There are many different types of salami depending on the region and the ingredients used. Some of the most well-known Italian varieties include Milano salami (Salame Milano) and the spicy Calabrese salami. Milano salami is milder in taste, while Calabrese salami is known for its spicy, strong flavor.

On pizza, salami is a popular choice because it adds a spicy and robust flavor that complements the dough and other ingredients. The slightly spicy note of the salami adds an extra dimension of flavor that many people love.

So, salami is not just a tasty ingredient, but it also has a long and proud history as one of the most versatile and popular meat products in the world.
