Really? I can tell you now that most British people (with that I include, English, Irish, Scotish, Welsh and Cornish people) have never even tried this..
HP sauce is a different matter - bacon is not the same without it!
Actually I was joking about certain British food...I am sure there are some really excellent dishes...When I lived in London, though, I found much of the take out food to be 'funny'...But the food in the supermarkets was good: Very good bread (many varieties/brands), good canned soup, excellent cheese, good meat...And if you go to real ethnic restaurants and neighborhoods, the food was very good...The best fast food?...the 'Beigle Bake' on Brick Lane...Hot fresh bread and rolls 365/24/7, and huge salt beef sandwiches w/English mustard, mayo or horseradish for 2 pounds...You can't finish the sandwich in one shot!
