After this time, form rolls of similar size, place them in a baking dish lined with parchment paper. Cover with a cotton cloth, let stand 30 minutes. Turn on the oven at 180º with fan and heat below.
With the tip of a knife, make a small cut in the center of the rolls so that the dough does not break during baking. Bake for 20 to 30 minutes or until golden brown. (rack in central guide). Let cool completely and serve.
