Wax-covered cheese is a type of cheese that is covered in a layer of wax to preserve it. Two popular types of wax-covered cheese are Edam and GOUDA, both of which are named after the Dutch cities where they originated. Edam is a semi-hard cheese made from cow's milk and has a mild flavor. GOUDA is a semi-hard cheese made from cow's milk and has a slightly sweet and nutty flavor. Both cheeses are often used in cooking and can be eaten on their own.
