In a large mixing bowl, whisk together flour, salt, and baking powder.
Add cubed butter to the flour. Cut the butter into the flour mixture, using a pastry cutter or fork, until the butter is pea-sized and distributed throughout.
Add milk to the flour mixture a little at a time, stirring with a fork, until all of the flour is moistened and large clumps form. You might not use all of the milk.
Transfer the dough onto a lightly floured work surface and press into a small, rough square.
Using a bench scraper, cut the dough into four equal parts. Stack them, and pat again into a rough square.
Cut this new square into four equal parts and stack them. Finally, roll or press the dough into a 1-inch thick sheet.
Cut the biscuit dough into 10 biscuits using a 2¼ inch round cutter or regular mouth jar.
Place the biscuits close together on a small baking tray or skillet.
Bake for 16 minutes or until the tops are golden brown.
Brush melted butter over the top of the biscuits and cool for 5 minutes before eating.
