Yum, Yum: What Fun! by Mara Bergman, illustrated by Nick Maland (Greenwillow, Jan 2009)
Pastry School in Paris by Cindy Neuschwander, illustrated by Brian Langdo (Holt, May 2009).
I've also been doing some research for an article and came across How to Save Your Tail by Mary Hanson (originally published by Schwartz & Wade in 2007). I remember putting it on a selection list for Queens librarians, but it still flew under my radar. Very Ratatouille-esque.
Keep in mind I haven't read any of these titles so I'm not recommending them at this time. But I don't think it's a coincidence that we're seeing so many new food-related books for kids at a time when feeding the world has become such a political (and trendy) topic.
