Grandma Pruit's Vinegar Pie is a classic Southern dessert that has been passed down through generations. It is a unique pie with a tangy and sweet flavor. The filling is made with a combination of vinegar, sugar, eggs, and butter, which creates a custard-like texture. The pie is baked until golden and set, resulting in a deliciously tart and creamy dessert. Serve it with a dollop of whipped cream or a scoop of vanilla ice cream for a perfect balance of flavors.
