If Joanne were stranded on a desert island and could only choose one vegetable, it would be onions. She would be literally lost without them! Today she's visiting McEvoy Olive Ranch in Western Marin County, and with her student Bridget, they'll make grilled coriander and cardamom dusted scallops, and farro risotto with caramelized onions and crisp shallots. Join them as they celebrate Alliums.
