This episode brings together physical chemistry, history, and food studies in search of the origins of a colonial Mexican fudge. In conversation with Gastronomica’s Jaclyn Rohel, Patrick Charbonneau, Jeffrey Pilcher, and Kelsey Kilgore discuss their unique collaboration and share the story of how they re-created the dish in the teaching kitchen of the University of Toronto’s Culinaria Research Centre. Drawing on manuscripts and published cookbooks from the 18th to 20th centuries, in combination with hands-on culinary experimentation, they trace the recipe to Mexican vernacular traditions of candy making.
