My name is Sofie Dimitriou, and if you ever find yourself walking through the narrow stone-paved streets of Thessaloniki at sunrise, you just might catch the warm scent of orange blossom and cinnamon drifting from my kitchen window. I’m 42 years old, and I’ve been baking since I was tall enough to see over my grandmother’s marble countertop, sneaking spoonfuls of galaktoboureko custard when I thought no one was watching.
