Zopf or Züpfe is a type of Swiss bread made from white flour, milk, egg, butter and yeast. The dough is brushed with egg yolk before baking, lending it its golden crust. It is baked in the form of a plait and traditionally eaten on Sunday mornings. A variant from Swabia is known as a Hefekranz (also: Hefezopf), and is distinguished from the Swiss Zopf in being sweet.
