Pancetta is made from pork side, the same cut used to make bacon. However, it's not smoked, and there's no sugar involved. Just garlic, salt and spices, in particular a liberal dose of freshly ground pepper. It's almost always used as an ingredient in other dishes, sometimes providing flavor, and other times taking a commanding role, for example pasta alla carbonara
or a rich pasta all'arrabbiata
