Maybe you're just using the wrong sources? I guess it's possible that websites don't exist for that, although I somehow doubt it. When I want the basic version of a traditional recipe, I use a cook book. Like the one I still have from high school cooking class. No experiments or fancy additions, just the basic stuff clearly put together.

There are still a lot of advantages for such a source compared to an LLM average. Cue all the many usual reasons why an LLM response might not be what you were looking for, even if you don't notice it.
