If there is a heaven for biscuit-lovers, it’s got to be a lot like Mamie’s. As you walk into the little restaurant at the edge of Conyers, look beyond the order counter into the kitchen. There, throughout the day, you will see biscuits being made by hand, one at a time, from dough pulled out of a big silver bowl. And you see big trays of golden brown ones hot from the oven, ready to serve. The biscuits you eat at Mamie’s are always warm and fresh, but it is possible that you may arrive at a moment in time when the ones you are about to receive are still baking. So you place your order and pay, then find a seat and wait. Soon before you will appear the fluffiest, tastiest, best-smelling biscuits you ever imagined.
