Proof the yeast: If using active dry yeast, combine the warm milk, sugar, and yeast in a large bowl. Let stand for 5 to 10 minutes until foamy. If using instant yeast, simply mix it with the flour and continue.
1 cup 240 ml warm milk, ¼ cup 50 g sugar, 2¼ teaspoons instant yeast
Mix the dough: Add the egg, melted butter, salt, and flour. Stir until a shaggy dough forms.
1 large egg, ¼ cup 60 g butter, melted and cooled, 1 teaspoon salt, 4 cups 480 g all-purpose flour
Knead: Knead by hand for 8 to 10 minutes, or with a stand mixer fitted with a dough hook for 5 to 6 minutes, until the dough is smooth and elastic.
First rise: Transfer the dough to a lightly greased bowl. Cover and let rise for about 1 hour, or until doubled in size.
Divide the dough: Turn the dough onto a lightly floured surface and divide into 12 equal pieces.
Shape the rolls: Shape each piece into a smooth ball and arrange them in a greased 9x13-inch baking dish.
Second rise: Cover and let rise for 30 to 45 minutes, or until the rolls are puffy and nearly doubled in size.
Bake: Bake at 350°F (180°C) for 20 to 22 minutes, or until golden brown.
Finish: Brush the warm rolls with melted butter, cool for about 10 minutes, and serve.
