The way I see it? The only countries this side of the pond who can honestly proclaim to have decent cuisine are the Italians and the French. There’s a B-tier of tryhards and then aaaaalllll the way down are the “we don’t have cuisines but we made some weird snacks and sweets?” and that’s us, Belgians, the Nordics. This D-tier is what the British aspire to.

Dunno about that. There's a lot of almost-regional foods people don't know about because they weren't a feature at British Bakeoff or something, like Eierschecke. Generally, the recipe pool is so vast, you could pick the most cursed town in Bavaria and probably still find a subset you'd enjoy eating regularly.

Hungarians have some amazing foods, if you adjust spices for your pallet. Ćwikła is a pan-slavic condiment that's just beet pulp mixed with horse radish that goes with anything. Liptauer is a cheese spread that can go from basic to divinely complex, depending on experience and ingredients. Same goes for pierogi. I have a door stopper of a book of old Polish recipes where, so far, substituting venison for tofu only required common sense adjustments and hasn't backfired yet.

EDIT: I know you meant 'cuisines' not 'recipes', but... where do you draw the line, really? Is pizza still Italian or just of the broadest Italian origin if most well-known variants are regional adaptations of US-spinoffs?

Balkans, Greece and Turkey are mixed almost as much as Slavs and Ashenazi, Prussians, Baltics, Germans... the reason most of them don't have a well-defined 'cuisine' is that they've been raided, taken over or displaced so many times it's almost meaningless to deliniate beyond etymology.
