You're probably right. It all depends on who is doing the cooking. If I made a dish it would be something fancier if a famous chef made it.Traditional "rules" are just a way of formalising and standardising peasant recipes for people with little imagination and culinary skill. Proper peasants use what's available at the time and don't follow recipe books. That's my opinion, anyway.
On arrival in Béganne, we astonished my in-laws with two "local" dishes they'd never heard of: Chili Concarneau and Spaghetti Bégannaise. Of course, I'd made them up, but they didn't know. They had driven for a whole hour into the very wilds of southern Brittany where civilisation is scarce, where we speak Gallo and write in bog runes.
Silly buglers!
Simple foods for a simple mind. They all taste the same.
Ribs on a stick, Mock chicken legs and pudgy pies!
