Activate the Yeast: Add the warm milk, warm water, sugar, and yeast to a bowl. Mix well, then leave the mixture undisturbed for 10 minutes.
Make the Dough: Add the all-purpose flour, salt, and oil to the yeast mixture. Knead the ingredients for 10 minutes until the dough begins coming together and becomes firmer. The dough will initially be sticky. Work the Sticky Dough: If needed, use the pull-and-bang technique by grabbing the dough, lifting and pulling it, then firmly banging it against the work surface before repeating. Continue until the dough becomes soft, smooth, and only slightly sticky. Incorporate the Butter: Add the chilled butter to the dough and knead for another 5 minutes. Continue until the butter is incorporated and the dough comes together into a smooth, cohesive dough. First Rise: Cover the dough and allow it to rise for 1½ to 2 hours, giving it time to develop and become ready for shaping.
Divide the Dough: Once the first rise is complete, divide the dough into 6 equal portions and shape each portion into a ball.
Shape the Rolls: Roll each dough ball into a piece approximately 6 inches wide and 9 inches long.The work surface should not require flour for rolling.Roll each piece into a 9-inch log and place the shaped dough on a baking sheet. Second Rise: Cover the shaped logs and let them rise again for 1 hour. This second rise helps the bread expand further during baking and contributes to a soft crumb. Preheat the Oven: Preheat the oven to 400°F (200°C) while the shaped rolls complete their second rise.
Bake the Fino Bread: Place the baking sheet in the preheated oven and bake the rolls for about 10 minutes, or until they become golden.
Cool the Rolls: Transfer the baked loaves to a cooling rack and allow them to cool.
Store the Bread: Once cooled, place the loaves in a Ziplock bag for storage.
