In a small bowl, combine warm water, 2 tablespoons of sugar, and the yeast and allow to proof until foamy, about five minutes. Meanwhile, scald the milk by heating it in a small saucepan over medium-high heat without stirring just until bubbles form around the edge of the pan and the milk starts to steam a bit. Remove from the heat and let cool for 10 minutes.
4 Tablespoons granulated sugar, 2 Tablespoons active dry yeast, 1/2 cup warm water, 1 1/3 cups whole milk
Once the yeast has proofed, stir in the other 2 tablespoons of sugar and the salt. Add eggs and slightly cooled scaled milk along with 2 cups of the flour and orange zest. Beat with the paddle attachment until smooth, about 2 minutes.
2 large eggs, 1 1/2 teaspoons salt, 5 cups all-purpose flour, 1 Tablespoon orange zest
Switch to the dough hook. Add remaining flour 1 cup at a time, kneading until a smooth, soft dough is formed, about 5 minutes on medium speed. Transfer the dough to a large greased bowl and cover tightly with plastic wrap. Let the dough rise for one hour or until doubled in size.
Roll out the dough into a large rectangle. Spread softened butter evenly over the surface of the dough, then sprinkle with granulated sugar and reserved orange zest.
1/2 cup salted butter, 1/2 cup granulated sugar, 2 Tablespoons orange zest
Fold one long edge of the dough over about 1/3 of the way, then do the same with the other side sort of like folding a piece of paper to fit in an envelope but lengthwise. Use a pizza cutter or sharp knife to cut into 16-20 strips that are about 1-inch wide.
Pick up one strip of dough and cross the ends over to form a loop. Push one end of the strip through the loop to form a knot and place the roll on a baking sheet.
Repeat with the remaining dough to shape all the rolls, then cover loosely with plastic wrap or a clean kitchen towel and let them rise for 30 minutes until puffy.
Bake at 400°F for 8-10 minutes or until lightly browned on top.
Make glaze by combining ingredients and whisking until smooth. Brush or drizzle glaze over the rolls, then let it set up for 30-45 minutes before serving.
1 1/2 cups powdered sugar, 1 Tablespoon orange zest, 2-3 Tablespoons orange juice
