Sweet potato pie is a type of pie. It is common in the southern United States. It is similar to pumpkin pie. It is common at Thanksgiving. It is a side dish or dessert.
"The most delicate root that may be eaten," as the sixteenth-century English mariner and slave trader John Hawkins called it, suited European taste. Henry VIII ate his sweet potatoes in heavily spiced and sugared pies, a fashion that survived at least until the 1680s."
