[2] Zwiebelkuchen is a favored autumn dish commonly enjoyed at wine festivals.

It is particularly popular in Germany's wine-producing regions, including Thuringia, Palatinate, Hessia, Franconia, Swabia, Alsace, and the Rhine and Moselle areas.

[3] Instant yeast and sugar are combined with lukewarm milk and left to sit for 10 minutes.

In a separate bowl, flour and salt are mixed together, followed by the addition of the yeast-milk mixture and vegetable oil.

The dough is then placed in a large, greased bowl, which is coated with cooking oil or nonstick spray.

Vegetable oil is heated in a frying pan, and the bacon cubes are cooked until crispy.
