I was pretty surprised at how good GPT-4 was at creating new recipes at first - I was trying things like "make dish X but for a vegan and someone with gluten intolerance, and give it a spicy twist" - and it produced things that were pretty decent.

Then I realized it's seen literally hundreds of thousands of cooking blogs etc, so it's effectively giving you the "average" version of any recipe you ask for - with your own customizations. And that's actually well within its capabilities to do a decent job of.

And let’s not forget that probably the most common type of comment on a recipe posted on the Internet is people sharing their additions or substitutions. I would bet there is some good ingredient customization data available there.
