St. Catherine's Taffy is a candy made by girls in French-Canadian families to honour St. Catherine, the patron saint of unmarried women on her feast day, November 25.[3] St. Catherine's day is sometimes known in Franco Canadian families as "taffy day", a day when marriage-age girls would make taffy for eligible boys.[4]Marguerite Bourgeoys, a founder of the Notre-Dame de Montréal and an early teacher at Ville-Marie, the colonial settlement that would later become Montreal, is credited with starting the tradition as a way of keeping the attention of her young students.[1][5]
