Crowdie is a Scottish cream cheese, or the term less often refers to a type of brose (an uncooked porridge).
The cheese is often eaten with oatcakes, and recommended before a ceilidh as it is said to alleviate the effects of whisky-drinking. The texture is soft and crumbly, the taste slightly sour. Like cottage cheese it is very low in fat, being made from skimmed milk.
A version of crowdie known as "Black Crowdie" or "Gruth Dubh" is made by rolling crowdie in a mixture of pinhead oatmeal and crushed black peppercorns.
