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.
