Who knew a simple bowl of soup could be so interesting? When a younger brother decides his soup is too hot to eat, he starts peppering his older brother with questions: Where do lentils come from? What are those white things? Why is it called celery? One question leads to another and another and another, and the older brother answers them all with humor and dwindling patience. Through questions, jokes and riddles, we learn about lentils, tomatoes, salt, pepper and everything else we need to make a good lentil soup, including a recipe for readers to make it themselves. This delightfully illustrated picture book will pique the interest of little connoisseurs everywhere and encourage inquisitive minds to think about what goes into their favorite foods.
