You could be right. Till the mid 60s, Curry was probably not uncommon in the UK due to the Indian Raj connections. But then it faded a bit; when I came to the UK in 1985, curry was not very popular and when I asked for coriander at the local Sainsbury's, they looked at me as thought I was a Martian. But today, it is a popular herb with the local English people who seem to indulge in their own version of the curry. Going back to my original question, I was under the (maybe wrong) impression that eating rice was considered beneath their upbringing for the upper classes. Since curries are usually eaten with rice, I assumed that they did not usually figure at rich folks' tables.
