I think tea, for example, still qualifies. Even though it is cheap/not posh. Because lots of people do position it as some sort of basic requirement for life and extol the benefits of a cup of tea.
plus there is plenty of overpriced, wanky tea out there too.
I simply don’t get it. I feel many British people rate tea far beyond its merits. I’m not saying it’s disgusting, just overrated.
I would imagine that other people might feel the same about, for example, Yorkshire puddings or gravy. People do make a big fuss about how incredible these things are/how they make the meal/etc. Other people will be thinking: really? I don’t understand why people rate this so highly.
in fact, the same might be said about the entire British roast dinner. I’m certain lots of people don’t understand why many people are so keen on them and rate them so highly.
I do agree, that it’s not really about foods people hate. But many of the foods listed are the kinds of foods people will list as incredible comfort food or such like (mashed potatoes, for example) that others might think are overrated on the basis that they’re horrible.
