Add the water, yeast, and sugar to a small bowl, and let the yeast bloom for a few minutes.
1½ cups water, 2¼ teaspoons active dry yeast, 1½ teaspoons granulated sugar
Add the flour, cornmeal, and salt to the bowl of a stand mixer fitted with the paddle attachment. Mix on low until combined.
3½ cups all-purpose flour, ½ cup yellow cornmeal, 1½ teaspoons kosher salt
Add in the yeast mixture and 2 tablespoons oil. Mix on low for a couple of minutes, until the dough comes together.
3 tablespoons olive oil
Add a tablespoon of olive oil to a large bowl. Transfer the dough to the bowl, toss it in the olive oil, cover with plastic wrap, and let it rest for 1½-2 hours, until it has doubled in size.
Transfer the dough to a floured work surface. Roll it out into a 9x12-inch rectangle.
Spread the butter over the dough. Then, roll the dough up to create a log, seam side down.
4 tablespoons unsalted butter
Fold the dough into thirds to create a small rectangle.
Cut the rectangle in half, and shape each piece into a ball.
Return the balls of dough to the bowl, and let rest in the refrigerator for 45 minutes.
