Swiss cheese generally refers to a group of cheeses originally from Switzerland, known for their distinctive appearance and flavor. The most famous type is Emmenthal (Emmental), characterized by its large holes or “eyes,” nutty and slightly sweet flavor, and firm yet pliable texture. Swiss cheeses are typically semi-hard, with a smooth texture and a mild to medium flavor profile. They’re popular for slicing, melting in dishes like fondue, or serving on cheese platters.
