Vánočka is a large braided sweet bread with raisins, traditional of Christmas in the Czech Republic.
Punch down the dough and turn over onto lightly floured board. Divide dough into 6 pieces. Roll each piece into a rope, about 14 inches long. On a baking sheet lined with parchment paper, braid the pieces loosely and pinch the ends together. Cover with a cloth or greased plastic wrap and let rise 60 to 90 minutes in a warm place.
Let cool completely before slicing. Dust with icing sugar before cutting, if desired.
