Jarlsberg has a distinctive sweet and nutty taste and is famous for its recognisable large, round holes. It is a mild, semi-soft cow's milk cheese and resembles Swiss Emmental cheese, though it does tend to be sweeter and stronger than Emmental. Jarlsberg is wonderfully versatile - whether it is bought to be used in sandwiches or as a tasty addition to your cheese board. Pasteurised and not suitable for vegetarians.
