I have such a soft spot for stack pie – a Southern American pie that came about when churchgoers took pies to functions, and stacked them up on top of each other as a mode of transport. They sliced them like a layer cake to serve. It was really more like a Tupperware solution than a considered dessert. This recipe uses a traditional chess pie, but I’ve replaced the frosting with thick layers of sour cream and raspberries to cut through the sweetness. It is dedicated to our fellow Feasties at the magazine – Anita, Lara, Dan, Alix, Rachel, Eloise and Dylan – who share our love of this heroic pie. — Phoebe
