The word "ethnic" is somewhat confusing.
I made toad in the hole yesterday using Lincolnshire sausages from the local farm shop and the eggs in the Yorkshire pudding batter were from next door's hens.
Two counties and a neighbour. Can't get more ethnic than that.
Tonight I am making a beef chilli stir fry from a recipe used the other week on the BBC Food and Drink programme. I suppose as the BBC must have a diversity policy, you can throw the word "ethnic" in when describing it?
