This discussion is a fine example of different strokes for different folks!
Personally, I LOVE having variations suggested to me. It stimulates my creativity. And I have never, ever had a problem using any of Bittman's recipes. For me, a few photos are nice, but I don't need photos to cook. I would rather have more pages of more recipes than devote a lot of room to pictures. If you are a beginner, a photo might help you know if you are on target, or it may be a discouraging, unattainable goal.
So the question is, what would the OP's niece most enjoy?
- a very clear set of instructions versus a cooking lesson/source of ideas?
- a smaller set of recipes (as one would usually find in a celebrity cookbook) versus a more comprehensive compendium?
For what it's worth, I gave the Bittman book to a friend's son when he left home for college. By all accounts he has found it very useful.
One final consideration. Books like Bittmans, or the Joy of Cooking or Fannie Farmer or The New Best Recipe all cover the familiar everyday food that the young woman might already enjoy and want to try and cook herself. The other books, while not difficult to cook from, do not start with the basics. They tend to be more focused on recipes that reflect the brand of the author and are less homey/more impressive (to serve to others) than things the OP's niece enjoys every day. If I had to choose between Fannie Farmer and Joy of Cooking I would go with Fannie Farmer, but I would choose either of those as a good book that covers all the basics. The one thing that might convince me to choose a celebrity cookbook as a gift to a young cook is if she already knows about and likes the celebrity.
