"The natural five week ripening process gives Frico Maasdam its delicious sweet and nutty taste. Due to its holes and taste this cheese is often referred to as Dutch Emmental. It can be added to any hot and cold dish, eaten as a snack or in a sandwich. It is also the perfect cheese for a cheese fondue. Frico Maasdam is recognisable by its slightly rounded cylinderrical shape and characteristic domed top. Within the cheese, holes are formed by gas produced inside the cheese during the ripening period."
