Sift together flour, baking powder, salt, and sugar in a large bowl.

Add shortening to the dry ingredients and mix lightly until the mixture resembles coarse crumbs.

In a separate bowl, beat the eggs and add the milk, whisking to combine.

Pour the egg and milk mixture slowly into the flour mixture, mixing gently until just combined.

Turn the dough out onto a lightly floured surface.

Roll the dough out to a 1/2-inch thickness.

Cut the dough into 2-inch squares.

Fold each square over into a 3-cornered piece (triangle).

Place the scones in a greased baking pan.

Brush the tops of the scones with milk.

Dust the scones with sugar.

Bake in a preheated oven at 400°F (200°C) for 20 minutes, or until golden brown.
