In a mixing bowl, combine the sifted flour, sugar, salt, and dry yeast.
Gradually add the warm water and vegetable oil, mixing until a soft dough forms.
Knead the dough for about 5 minutes until smooth, then cover and let it rest for 10 minutes.
Lightly flour a surface, shape the dough into a loaf, and place it on a baking tray. Cover and let it rise for 20-30 minutes.
Preheat the oven to 375°F (190°C). Brush the top of the dough with milk and bake for 20-25 minutes, or until golden brown.
Remove from the oven and immediately brush with butter for a soft, glossy crust.
Let cool slightly before slicing and serving.
