Also like, forget amounts, cook times are super important and not always intuitive. If you screw them up you have to throw out all your work and order take out.
For one an AI generated recipe could be something that no human could possibly like, whereas the human recipe comes with at least one recommendation (assuming good faith on the source, which you're doing anyway LLM or not).
Also an LLM may generate things that are downright inedible or even toxic, though the latter is probably unlikely even if possible.
I personally would never want to spend roughly an hour or so making bad food from a hallucinated recipe wasting my ingredients in the process, when I could have spent at most 2 extra minutes scrolling down to find the recommended recipe to avoid those issues. But to each their own I guess.
And yes cook times are important but no, even for a human-written recipe you need the intuition to apply adjustments. A recipe might be written presuming a powerful gas burner but you have a cheap underpowered electric. Or the recipe asks for a convection oven but your oven doesn't have the feature. Or the recipe presumes a 1100W microwave but you have a 1600W one. You stand by the food while it cooks. You use a food thermometer if needed.
