The photos in this book are fantastic and draw the eye, though it is important to note that with a few exceptions they are stock images and may not reflect what the recipes actually look like. Side by side, the quality difference is noticeable between the author's photos and the professionally taken and edited ones, though when viewed independently they are still clear and informative.
In general I would recommend this book as a standard children's cookbook intended for littles to cook alongside their parents, do basic prep work and clean up. I wouldn't say this is truly a Harry Potter cookbook though, since the bulk of the non-snack recipes are not featured anywhere in the series and they seem a little misplaced with the theme. However, for learning to read recipes and dabble in the mundane magic that is the kitchen this book is absolutely worth a look - and who knows, maybe it will inspire a few more kitchen magicians to follow their culinary dreams!
