Activate the Yeast: In a small bowl, combine the warm milk, granulated sugar, and active dry yeast. Stir gently and allow it to sit for 5-10 minutes, or until it becomes frothy on the surface, indicating that the yeast is active.
Prepare the Dough: In a large mixing bowl, whisk together the all-purpose flour, salt, and lemon zest. Create a well in the center and pour in the frothy yeast mixture, the melted butter, and the eggs.
Combine Ingredients: Stir the ingredients together until they begin to form a cohesive dough. Transfer the dough to a lightly floured surface and knead for 5-7 minutes, until it is smooth and elastic to the touch.
First Rise: Place the kneaded dough into a greased bowl and cover it with a clean kitchen towel. Allow it to rise in a warm, draft-free area for about 1 hour, or until the dough has doubled in size.
Shape the Rolls: Once the dough has risen, gently punch it down to release any air bubbles. Roll it out on a floured surface into a large rectangle, approximately 12x18 inches.
Add Blueberries: Evenly distribute the fresh blueberries over the surface of the dough. From the longer side, tightly roll the dough into a log, ensuring the blueberries are well encased. Pinch the seams closed to secure the filling.
Slice and Second Rise: Using a sharp knife, slice the log into 12 equal pieces. Arrange the slices in a greased baking dish, cut side up. Cover with a towel and let them rise for another 30 minutes.
Bake: Preheat your oven to 350°F (175°C). Once preheated, place the baking dish in the oven and bake the rolls for 25-30 minutes, or until they are golden brown and puffy.
Make the Glaze: While the rolls are baking, prepare the glaze by whisking together the powdered sugar and fresh lemon juice in a small bowl until it reaches a smooth consistency.
Finish and Serve: Once the rolls have finished baking, allow them to cool in the pan for about 10 minutes. Drizzle the lemon glaze generously over the warm rolls for a delightful finish.
Notes
Serve the warm rolls on a decorative platter. For an elegant touch, garnish with a sprinkle of fresh lemon zest and additional blueberries.
