Your Hosts

Greta Halloran & Dr. Owen Pace

Greta spent **38 years** running a neighborhood bakery before hanging up her apron; Owen is a **food scientist** who studies wild yeast for a living. We started The Sourdough Hour because every baking show was either pure nostalgia or pure lab coat — we wanted one with both flour on the bench and a thermometer in the dough. Baked weekly from a tiny kitchen. Notes and recipes at [sourdoughhour.fm](https://sourdoughhour.fm).
