The reputation comes from the US military being stationed in the UK during the height of WW2 rationing when there was an extremely limited list of ingredients to cook with. They were unable to associate a country under an attempted siege from U-boats with a reduced supply of food.
We do have a love of beige food at times, but it’s essentially our version of chicken tendies.
Ahhh, that makes sense. Kinda rough that the rep hasn’t gone away yet, though.
It’s the same with English beer. On the continent, people keep saying that Brits drink their beer lukewarm. When I was there, they actually had temperature displays at the tap in most pubs that usually showed something around 4°C (~39°F). For reference, that was in the Huddersfield area (between Leeds and Manchester) around 15 years ago.
