I ended up eating haddock and chips in Bridlington last weekend with my French friends who were over for a week visiting.
Rather than opting for my normal sausage, saveloy or pukka pie option, I felt strangely obligated to order fish (which I haven't liked since I was about 7) in order to prove to my friends that British fish and chips is good.
Is there a statistically significant link between patriotism and more adventurous eating? I very much doubt it. It's not like I don't retry stuff fairly often anyway (I tried some other seafood a couple of months back and disliked it as much as ever.) I guess white fish just doesn't taste that fishy - which is why (having eating the haddock) I have now decided I can actually eat it without grimacing.
