Step 1

Dissolve the yeast in 1/2 cup warm water for about 1 minute. No need to use a thermometer for the water’s temperature, but to be precise: about 105°F (41°C)-115°F (46°C). Stir the yeast/water around. Then add orange zest, orange juice, sugar, salt, egg, butter, and 1.5 cups of flour. Beat everything together on low with a handheld mixer, scraping down the sides as needed. (A mixer is definitely needed to break up all the butter and beat everything to the proper consistency.) With a wooden spoon, stir in enough of the remaining flour to make a dough easy to handle – about 1.5 – 2 more cups. You are looking for a dough that is not sticky and will spring back when poked with a finger.

Step 2

Transfer the dough to a lightly floured surface and knead it with your hands for about 5-6 minutes. Form the dough into a ball and transfer it to a lightly greased bowl. Cover the dough and let sit in a warm place until doubled in size, about 1.5 hours.

Step 3

Line the bottom of a 9×13 inch baking dish with parchment paper, leaving room on the sides. Turn the dough out onto a lightly floured work surface and, using a rolling in, roll into a 10×15 inch rectangle. I used a ruler for accuracy. Make sure the dough is smooth and evenly thick, even at the corners.

Step 4

in a small bowl, mix together sugar and cinnamon. Spread the dough rectangle with softened butter and sprinkle generously with all of the cinnamon-sugar mixture. Tightly roll up the dough and cut into 16 even rolls (1 inch in width each) with a very sharp knife. Arrange them in the prepared baking pan, cut sides up.

Step 5

Cover the rolls and let them rise in a warm place for about 30 minutes – 1 hour.

Step 6

Preheat the oven to 375°F (191°C). Cover the rolls with aluminum foil and bake for about 25-30 minutes, until they are lightly golden in color. Transfer the pan to a rack to cool for about 15 minutes.

Step 7

In a small bowl, mix together all of the glaze ingredients and drizzle over rolls before serving. Add more orange juice to thin out, if needed.
