Brooke Siem baked with grandmothers around the world for her Grandmother Project, including with Sofy in Buenos Aires, where she learned this Argentinian take on bread pudding. It tastes like a magical mashup of French toast, cheesecake and flan. The caramel is made directly in the pan you bake the pudding in (one less dish to wash!), so you'll need a metal cake pan or pie plate. Sofy uses Wonder Bread, but any soft white sandwich bread will produce luscious results. Learn more about this recipe and other recipes Siem learned as part of her project in the article How Cooking Connected One Chef with Grandmothers Across the World.
