Everyday British food IMHO is hard to beat as mostly it is fresh meat and fresh veg and only ruined by the skills or lack of skills of the cook.
Many complain about lack of spices or herbs - traditional British cooking uses plenty of both but does not drown the delicate flavour of fish or some meat to extent you cannot taste it. Often highly spiced or herbed dishes in the past were to disguise the fact that the meat was either poor quality or had gone off.
You’re right, there’s lots of great food, great ingredients, wine and great restaurants in England now.
And I can never seem to make my tea here as good as a good English cuppa, and I buy Yorkshire Tea bags (here in America) made by Betty’s Tea Room’s at my local “gourmet” (hate the word) market. The Yorkshire tea is really rich tasting. Sometimes I use PG Tips also.
Real scones instead of those giant things we have here. The milk, eggs, butter and clotted cream are great. British cheese is underestimated also. There’s good pub food now too.
My problem is that the prices of a meal in a restaurant, hotel rooms, etc seem God awful expensive to the less than rich Americans.
And what I like about the Brits is that they are such great and interesting talkers. They can talk your arm off.
