A naive hope perhaps, but this ignores the risk of LLMs just creating a bad recipe based on the blind combination of various recipes in their training data.
For a super simple example, if you don't properly handle or cook raw meat then you risk getting sick even though the food might not immediately taste bad. Maybe that's obvious to you but might not be to the person preparing the food. Another example: Rhubarb pie is supposed to be made with the leaves and not the stalk because the stalk is poisonous and can cause illness. Just kidding, it's actually the other way around but if you were just reading a ChatGPT recipe that made that mistake maybe you wouldn't have caught it.
