I would have considered the name of the book to be arrogant, but JC could get away with it.
I don't have Julia Child's Mastering the Art of French Cooking. I became a fan of JC from watching her on TV. I got another of her books, The Way to Cook. I do still use some of those recipes. I would have considered the name of the book to be arrogant, but JC could get away with it. She was that good.
