Sachertorte
The first cake was made by Franz Sacher in 1832 when Klemens Fürst Metternich ordered the kitchen to create a new sweet for his evening guests. The chef was ill so Sacher, who was apprentice in his second year, invented the first Sachertorte. After this the cake was nearly forgotten. Sacher worked in Budapest and Presburg and opened in 1848 a  high-class delicatessen and winery in Vienna. His son Eduard Sacher, who learned in the  Demel bakery which supplyed the court, brought the recipe in the form we know today. First the cake was sold by Demel, but after Eduard bought the Hotel Sacher also there.
