Title: View the difference between a sweet potato and yam
Review: I don't think this book does a very good job a describing the difference between a "sweet potato" (almost did a Dan Quayle) and a yam. Some pictures in the book would have been helpful. ... There are several sources, one in particular with illustrations. I was quite surprised to see that a real yam is black/brown. ...I'm very curious to know how many people have been eating sweet potatoes while thinking they were eating yams.
