On today's show, we explore research on food pairing and flavor networks.

Earth Eats Associate Producer Alex Chambers walks us through the work of Dr. Yong-Yeol Ahn,(he goes by YY). Dr. Ahn is a professor of informatics and computing at Indiana University and co-creator of a fascinating map of flavor networks.

Anthropologists Maddie Chera and Leigh Bush talk with him about what these networks can, and cannot tell us about cultural food pairing preferences.

Harvest Public Media has a story about some special midwestern grapes, and Chef Daniel Orr has ideas for grape leaves, plus a surprising preparation involving rhubarb and strawberries.
