There are many geographically indicated foods of the United Kingdom.
In British cuisine, there is a custom of naming foodstuffs with reference to their place of origin.
However, there are other reasons for this practice; Scotch egg, which was invented in London and Dover sole which indicates where they were landed, for example.
A number of such foods have been granted Protected Geographical Status under European Union law (see List of United Kingdom food and drink products with protected status).
