Are you going to localize this? Using US recipes works only okay-ish: I usually have to figure out local substitutions for some ingredients, and transform units.
Anyway, amazing idea and I absolutely feel you. Recipe sites (and search engine results) are cluttered like hell, that's why I started collecting recipes in Mealie. But in practice this merely bumped my pool from "five fallback meals" to "10 usual recipes, which mostly cover my eating preferences since I'm the only one in the household putting recipes into Mealie".
I will eventually. For now I rely on browser translations which work most of the time. My biggest focus right now is on recipe quality and getting the right mix as well as the AI mode.
