-
To make the dough: Weigh your flour; or measure it by gently spooning it into a cup, then sweeping off any excess. Combine all the ingredients and mix and knead to make a smooth, supple dough.
-
Place the dough in a lightly greased bowl, cover, and allow it to rise until it has just about doubled, 60 to 90 minutes.
-
To make the filling: While the dough is rising, combine the orange juice, brown sugar, and both types of cranberries in a small saucepan set over medium-low heat.
-
Cook the mixture, stirring occasionally, until it begins to thicken to a jam-like consistency, about 10 to 15 minutes.
-
Remove the pan from the heat and stir in the melted butter, orange oil or grated rind, and spice.
-
Transfer the cranberry mixture to a heat-safe bowl and allow it to cool to room temperature.
-
To shape the loaf: Transfer the dough to a lightly greased work surface, and roll it into a 12" x 14" rectangle.
-
Spread the cranberry filling over the surface of the dough, leaving a 1/2" border along the edge of one of the short sides. Sprinkle Orange Jammy Bits evenly over the filling.
-
Starting with the filling-covered short edge, roll the dough up jelly-roll style, sealing the edge.
-
Cut the log in half lengthwise to expose the filling. Place each half side by side, filled sides up.
-
Keeping the filled sides up, twist or braid the two logs together, working from the center to each end.
-
Pinch the ends together, and place the twisted log in a lightly greased 9" x 5" loaf pan.
-
Cover the loaf and allow it to rise for 45 to 60 minutes, until it's crowned 1/2" to 1" over the rim of the pan. Towards the end of the rising time, preheat the oven to 350°F.
-
Bake the babka for 45 to 50 minutes, tenting it with aluminum foil about halfway through baking to prevent over-browning. The top of the finished loaf will be golden brown, and a digital thermometer inserted into the center of the loaf will read 190°F or above.
-
Remove the loaf from the oven. For a softer crust, brush the top of the loaf with melted butter, if desired. After 10 minutes, remove the babka from the pan and transfer it to a rack to cool completely.
