I’ve been waiting for this to happen. Britain has been culturally appropriating curries. Of course, they are right to an extent, but the next issue is a kind of intersectional one. Who becomes the arbiter of what constitutes a true dish? For example, Italian dishes will vary considerably from village to village - even household to household. Chicken tikka masala is commonly believed to have been invented in Britain, although by Bengali chefs, which really muddies the waters over who claims ownership. Perhaps some kind of French terroir system could be introduced where the key elements of a curry could be generally accepted and chefs would have to adhere to those or call the curry a different name?
Marks and Sparks are on the receiving end of the majority of righteous fury for their ready meal curries. I suppose it was going to be either them or Waitrose in the Grauniad. I’m not sure how any ready meal could ever be authentic. They’re all basically slightly shit food for extremely lazy people.
