Ingredients

Directions

Roll out the prepared dough into long narrow strips.
Twist each strip and coil it like a watch spring.
Place on pans, let rise, wash with egg, and bake.
For an alternative method, roll out dough into a thin sheet about ¼ inch thick and 12 inches wide.
Brush the sheet with melted butter, then sprinkle with currants, chopped almonds, citron, powdered sugar, and cinnamon.
Roll up the sheet like a jelly roll and brush the outside with butter.
Cut the roll into slices about ½ inch thick and place cut side up on pans.
Let rise, wash with egg, and either ice after baking or sprinkle with sugar before baking.
