I think it is. I'd say about 99% of my friends cook well, maybe half of them extremely well. I'd place myself somewhere between those two groups (based on others' comments about my food!). Pretty much all of my friends are adventurous about food and take pride in the food that they produce. Surely I can't be part of an abnormal set of 'Brits that can actually cook'?
Oh, and one thing that really gets up my nose is the otherwise brilliant comedy Frasier - all the jokes about Daphne's food being crap because it's British. Because American food's so amazing, clearly. I spent 2 weeks in the USA, ate out every night (otherwise it was a host's home cooking), and all of us Brits were seriously underwhelmed by the food. Most of it was nice (apart from the diner - what in the world are 'grits'??? They're actually gritty! ), but nothing special. Okay, rant over .
