In 1980, Kathleen Wall landed a 10-week, seasonal job working in costume at Plimoth Plantation in Plymouth. She’s still playing a Pilgrim today. “I have sort of become the guest who came to dinner and didn’t go away,” says the Pembroke native. Twelve years ago, Wall took over as the Colonial Foodways Culinarian, overseeing the food exhibits in which visitors step into Pilgrims’ homes, where there’s often a live fire to cook dinner. Health Department restrictions say visitors can’t sample the food they watch being cooked, but they receive lessons in how the Pilgrims ate.
