Blueberries are Julie Elkind’s madeleines. They trigger memories of childhood summer days spent picking berries and baking with her much loved grandmother. There’s the day she’ll never forget when the blueberry cobbler they were baking exploded all over the oven. “It blew the oven door open and splattered all over the walls and the floor. We were covered head-to-toe in blueberries. We just laughed and laughed hysterically, and then started eating it off the counter tops,” she recalls.
