I don’t know if you think the colloquial use aligns more with what you said, but in Finnish cuisine is just “keittiö” (as in suomalainen keittiö) or ruokakulttuuri. English word is much the same in that it actually doesn’t just mean something fancy, even though as a French origin word it can seem like a fancy word.

I’m just going with that. It’s not a personal preference thing. I like Finnish food but it doesn’t really matter to me if the term cuisine was reserved for just fancy. I was just saying.
