Zwiebelkuchen
When the grape harvest starts in Baden and the Württemberg vineyards in September, bakeries pull out trays of Zwiebelkuchen: a thin yeast base piled with slowly softened onions under a sour-cream and egg custard, sprinkled with caraway. It is traditionally eaten warm with Neuer Wein or Federweißer, the young, still-fermenting wine; that is alcoholic, so pour cloudy fresh grape juice or apple juice instead, which tastes just as right. Many bakers add bacon; this version is vegetarian. A common mistake is rushing the onions on a high heat: they need 25 minutes on low until soft and sweet but still pale. Chef's tip: cool the onions before adding the custard, or the eggs start setting in the bowl.
