If they're asking an LLM for a recipe, they don't.

My wife does it all the time, and it's actually decent.

That's just pure nonsense. My partner is very competent cook and she invents new recipes and experiments all the time. I don't see why she can't use LLM output as an inspiration to combine with her own expertise, sense of taste, and preferences to come up with an excellent dish.

That's quite an assertion.
