On first reading, this picture book is the story of Minnesota twins, making sweet potato pie with mama. They shop at the farmers market—and they peel, mix, taste and try to guess mama’s secret ingredient. But like a sweet potato pie itself, this story is more than it appears. It’s also an invitation to bake together, serve others and remember to have a good laugh. Playfulness and family coziness come through in the text and in the warm illustrations by local artist Christopheraaron Deanes.
