Given how much it seems to matter to you that fish head soup is a thing because you found it in a book, I retract my entire ‘point and argument’. It’s clearly as British as red double decker buses, fish and chips, self-deprecation, a vague sense of unease at our politicians behaving as if our country is in some way still important, kilts, Cornish pasties, lava bread and cockles, and an Ulster fry. You obviously know more about British food than I do, and are expert in all things and definitely not. to. be. trifled with. whereas I have probably never eaten food in my entire life. You’ve won a disagreement on the internet and will be able to feel powerful and vital for the rest of your day.
