Heat the milk to 115 degrees F. Sprinkle the yeast on top and let stand for at least 5 minutes, until you see bubbles.

Grate the zest from the orange. Add the zest, butter, egg, sugar, and salt to the yeast mixture. Stir to combine.

Stir in the flour, 1 cup at a time, until the dough comes together.

Knead the dough for 5 minutes. It will become less sticky but still be very sticky. Resist the urge to add more flour.

Butter a large bowl. Scrape all the dough off the counter and into the bowl. Cover with a damp towel and let rise in a warm place until doubled, about 30-45 minutes.

Meanwhile, mix all the filling ingredients together until thoroughly combined.

Tip the risen dough out onto a well-floured work surface, and generously sprinkle the dough with more flour. Roll out the dough into a rectangle, about 16 inches by 12 inches (size not exact!).

Dollop the filling over the dough and then spread it into a thin, even layer.

Starting at a long edge, use a dough scraper or metal spatula to help you roll up the dough into a log.

Generously butter a 12 inch pie dish (or another baking pan approximately that size).

Cut the log into 8 equal pieces. Arrange them in the pie pan so you can see the spiral of filling, one roll in the middle and the rest in a circle around it.

Brush the rolls with warm milk so they don’t dry out. Let rise in a warm place for about 20 minutes.

Preheat the oven to 375 degrees F.

Bake the rolls for 20-22 minutes. If they look very brown after 18 minutes, put foil on top to prevent further browning.

While the rolls are cooling, make the glaze by beating the powdered sugar and orange juice together until no lumps remain.

When the rolls have cooled for at least 20 minutes, drizzle the glaze on top. (The longer you wait before glazing, the less the rolls will absorb the glaze.)
