Making Jam with Grandma Kathy and Great-Grandma Kay (06:12)

This is a special episode of Cooking with Grandma, featuring four generations—Kay, Kathy, Astrid, and Kaatje—who pick blackberries and make jam together. To make your own jam, use this CHOW blueberry jam recipe, substituting blackberries for blueberries. Special thanks to the crew at Eat Real for introducing us to Kathy Kensinger and her family.
