Interesting question. I have not made any exploration into the eating habits of the English. I was fortunate during my childhood not to go hungry, but from a social point of view, as we live on an island we have imported most of our food for hundreds of years - probably rising now to 75% or more. Our government has blindly promoted importation of food and building on our agricultural ground. Even after two world wars they refuse to learn the lesson and now import people instead as is happening in America and Europe. So, given the expense of food, the high cost, the lack of culinary imagination of the English, and their (not mine!) ability to consume fast food, corn on top of pizza is probably seen as upperclass international cuisine in much the same way that they are in awe of the French eating snails, or the Americans frying SPAM. When we are all starving, I’m sure our diet will not be so fussy. As for pizza, I make my own if I want one, with anchovies sun dried tomatoes, cheese, more anchovies, more cheese, extra cheese, garlic, German sausage, Parma ham, cheese, a bit more cheese, various herbs, my own pastry base, with cheese melted in to the pastry, parsley, white wine, salt, pepper, more cheese, onion, more garlic and lastly, a garnish of cheese. No corn I’m sad to say.
