Berlin-based food writer Luisa Weiss is the author of "My Berlin Kitchen," a food memoir about growing up between Berlin and Boston, and founder of the beloved food blog, “The Wednesday Chef.” Watch as she demonstrates how to make Sachertorte, Austria’s most famous chocolate dessert. Using a recipe from her cookbook “Classic German Baking,” Luisa walks us through the importance of each ingredient while also sharing some of the history behind this Viennese delicacy, which many believe was invented by 16-year-old pastry chef Franz Sacher in 1832 for Prince von Metternich.
