All in Just One Cookie by Susan E. Goodman, illustrated by Timothy Bush
This is the book I’ve been looking for! At the beginning of the summer, when I was assembling the Summer Jar, I had the idea of doing things like baking cookies, but learning while we did it, mostly learning about food chemistry and how cookies become cookies. I actually looked around for some adult food chemistry books, but didn’t find anything useful. And there, all along, in our library, was this book, which was exactly what I had in mind.
All in Just One Cookie is about Grandma, her researching cat, and her hungry dog, who are making chocolate chip cookies. With each ingredient added, the cat and dog find out where the ingredient comes from, how it is harvested, and what it does for the cookie. There’s even a bit about how dogs and cats can’t eat chocolate. The kids were totally enthralled with the story of what makes a cookie, and I actually learned some stuff myself (like where baking soda comes from).
