At the venerable Café Hawelka, the witching hour is 10 P.M., not midnight, for that is when the pastry chef’s Buchteln hit the tables. In a matter of minutes, they magically disappear. Sure, you can enjoy these sweet rolls filled with preserves at room temperature at any time of the day, but served warm from the oven late at night, they are unsurpassable. They use a good amount of butter—in fact, many recipes say they should swim in the butter during baking. Thanks to Herr Schrammel at the Berufsschule für Bäcker und Konditoren for his recipe.
