One of the common things that the US and UK share is that we are both melting pots of culture. The US because we are a country almost entirely made up of immigrants and the UK because once upon a time they conquered the world. Each country has its own traditional foods that they consider theirs. Example:
US- Fish and chips
UK- Apple Pie (wait Chaucer cites an apple pie recipe... ) I mean buffalo wings
Well as seen above both cultures love to claim other cultures foods as their own. The most popular dish in the UK is Chicken Tikka Masala- an Indian dish so anglo-ized it is hardly recognizable. So one would think a trip to the grocery store would be a journey through 1000 lands.
Well going to cook a tasty meal of antipasto and eggplant parm I was regulated to the "international" isle for ingredients. Where 1/2 of what I wanted was not even there... and I had to make random substitutions. Luckily I was cooking for boys in their 20s and they will eat just about anything... and it did turn out alright.
I have already given up my diet coke for "squash" and just about all snack foods that I eat. I guess the US melting pot has a few different flavors than the UKs.
