“Whiskey in a teacup.” That’s how the owners of Buttermilk Sky Pie Shop describe their maternal grandmothers, whose spunk matched their poise step for step. And while there’s no booze in the recipes here, that metaphor rings just as true for the menu as it does for the grandmotherly women who inspired it. In other words, you’ll find dignified classics, including buttermilk and apple, sitting alongside creations that gleefully buck convention, such as a seasonal s’more pie with brownie filling and marshmallow meringue that swaps out a traditional crust for a buttery graham cracker base. Then there’s the I-40 pie—a pecan pie on steroids, which decadently tosses chocolate chips, toasted coconut, and sweet shortbread crust into the mix.
