Black pudding is often grilled, fried, baked or boiled in its skin. It can be eaten cold as it is cooked in production.
It was occasionally flavoured with pennyroyal, differing from continental European versions in its relatively limited range of ingredients and reliance on oatmeal and barley instead of onions or chitterlings to absorb and be mixed with the blood.
In the United Kingdom, black pudding is considered a delicacy in the Black Country, the West Midlands, Stornoway, the North West of England, and especially in Lancashire (in towns such as Bury), where it is traditionally boiled and served with malt vinegar out of paper wrapping. The Stornoway black pudding, made in the Western Isles of Scotland, has been granted Protected Geographical Indicator of Origin status. In the wake of this designation, butchers in Bury sought to demonstrate their history of manufacturing and selling the product. One such claim dates back to 1810.
Black puddings are also served sliced and fried or grilled as part of a traditional full breakfast in much of the UK and Ireland, a tradition that followed British and Irish emigrants around the world. Black pudding is now part of the local cuisine of the Canadian provinces of Nova Scotia and Newfoundland and Labrador.
In Scotland and the north of England, chip shops commonly sell black pudding battered and deep-fried. Prepared in this way, it is eaten as a meal with chips, replacing the better-known battered fish.
