Using yeast is the most common approach to making Czech Christmas bread (Vánočka). It requires two separate risings during the preparation process. From beginning to end, set aside at least 4 ½ hours to make. This recipe makes a long loaf with between 16 and 20 servings.
For a brief history of this Czech holiday staple, see my post Vánočka (Czech Christmas Bread) – Brief history and recipes. It references the recipe below, as well as an appealing yeast-free version that includes farmers cheese. Enjoy!
