How to Make It
Bring milk to a simmer in a small saucepan over medium, stirring occasionally. Gradually add 2/3 cup of the cornmeal, whisking constantly. Reduce heat to low, and cook, whisking constantly, until mixture thickens to a porridge-like consistency, about 30 seconds. Transfer mixture to a medium bowl. Let cool 10 minutes.
Meanwhile, combine yeast, water, and 1 teaspoon of the sugar in a small bowl. Let stand until foamy, about 5 minutes.
Place eggs, salt, and remaining 1/3 cup sugar in the bowl of a heavy-duty electric stand mixer fitted with a dough hook; stir to combine. Add cornmeal mixture, yeast mixture, and 1/2 cup of the melted butter; beat on medium speed until combined, about 1 minute. Reduce speed to low, and, with mixer running, gradually add flour, beating until dough pulls away from sides of bowl, about 6 minutes. (Dough will be lumpy.) Transfer to a lightly floured surface, and knead until dough is smooth, 3 to 4 minutes. Place dough in a large, lightly greased bowl, turning to grease top. Cover with plastic wrap, and chill 8 hours or up to overnight.
Turn dough out onto a lightly floured surface. Divide dough in half, and shape each half into a ball. Roll dough ball into a 13-inch circle; cut into 8 wedges. Brush excess flour from wedges. Roll or stretch each wedge into a 9-inch-long triangle. Starting from wide end, roll up each triangle, and place, point side down, 3 inches apart on 2 parchment paper-lined baking sheets. Curve ends to form crescents. Repeat with remaining dough half. Cover loosely with plastic wrap, and let rise in a warm place (80°F to 85°F) until doubled in volume, 1 hour to 1 1/2 hours.
Preheat oven to 350°F. Bake rolls until golden brown, 18 to 20 minutes. Brush with remaining 1/4 cup butter, and sprinkle with remaining 1 1/2 tablespoons cornmeal. Serve warm.
