I'm more worried about picture accuracy: usually the benefit of pictures in recipes is to see what you're aiming at (eg, how finely chopped something is), but I don't know if the image model is up to that level of detail.
As a highly literate person, it is easy to overestimate the share of the population that is highly literate.
Yes, pictures OF THE FOOD. Not unrelated pictures of another lamb-roast made with another recipe.
Good cookbooks do proper food photography, of the food made with the recipe. That's what sets them apart from slop, be it human or AI slop, cook books.
For almost everything else we can create them - just give a reasonable cook a kitchen and the ingredients and they will do it. For a picture we then have an artist do preparation to make it look good, but they should always start with the real dish.
