There are virtually no combinations of food which are toxic, you can mix any food with any food and, while it might not be good, it will still be food. (The only exception I know of is alcohol and mushrooms containing coprine, e.g. inky caps)
Point is, unless you're stupid enough to add glue or broken glass to your meal just because a recipe told you to, it's perfectly safe. More than just safe, LLM recipes these days are utterly boring in their normalacy, and, unlike cookbook recipes, can dynamically adapt to what you actually have in your pantry.
What really sucks is that Google pushed actual content creators out of the way in the first place. That is horrible. I think they should be challenged on this. Food bloggers, recipe writers, and creators have helped shape a huge amount of food culture, and they deserve to be protected rather than erased. If this kind of theft continues from the AI industry Im not sure what type of culture is is going to be left or what it is going to replace it to. I hope humanity is going to find a creative way around it, but I’m also aware how easy to manipulated the masses are.
