Hard cheese is a type of cheese that has been aged for a longer period of time, resulting in a harder texture and stronger flavor. Edam, Asiago, Romano, and CHEDDAR are all examples of hard cheeses. Edam is a semi-hard cheese originating from the Netherlands, Asiago is an Italian cheese made from cow's milk, Romano is an Italian cheese made from sheep's milk, and CHEDDAR is a hard cheese originating from England.
