Cutting the Curd with Anne Saxelby
If there is one thing Anne Saxelby knows, its cheese. Cutting the Curd, heard every other Sunday on HRN, finds Anne disseminating that dairy know-how to the listening public. Every episode also includes guests from the world of dairy, ranging from historians to farmers, chefs to cheese mongers, all engaging in dairy discourse so that you might gain a better understanding (and a better block) of this thing we call cheese.
