. Warm to 95-110 degrees F (35-40 degrees C) in the microwave using 30-second intervals.

Preheat oven to 400 degrees F (200 degrees C).
Remove dough from bowl to a clean work surface. Knead 2-3 times by hand to remove the air.
Divide dough into 12 equal portions of 55-58 grams each. Roll into balls and place on a parchment lined baking tray 1/4-inch apart. Cover with oiled plastic wrap or kitchen towel and allow to rise for 45 minutes.
