Leicester is famous for its eponymous cheese, which is made in a similar process to Cheddar.
Leicester is a hard cheese, made of cow's milk, with a bright orange or orange-red natural rind. The rind is usually dusted with thin powdery mold.
Leicester is rich in flavour and flakey like good Cheddar. It has a sharp "tasty" flavour, and a wonderful orange colour due to the addition of the natural dye annatto.
The cheese is best when aged for six to nine months. It is generally considered to be a table cheese, and is really excellent for cooking, grilling, and adding to sauces, where it adds a wonderfully dry sharp chalky flavour. Leicester has a fat content of 48%.
