British cuisine has some interesting side effects of World War II.

In the UK, today, people specifically desire beans produced by a factory, from a tin, with sugary orange-colored tomato sauce. Even at high end restaurants, people desire and expect tinned beans.

Whereas places outside the UK that share some elements of British culture like Australia, Boston and Ireland expect home made means - crushed tomatoes, borlotti beans, local additions (like feta and mint in Australia).

My best-guess understanding is the British taste for sweet canned beans comes from WW2 rationing.
