Line a large baking tray with parchment paper or a silicone mat and set aside. Preheat the oven to 300 degrees F.

Sift the flour, salt, sugar, and baking powder into a large bowl. Cut the butter into small cubes and rub it into the flour with your hands. In a medium bowl, lightly beat the eggs, and then add the milk. Pour the egg mixture into the flour mixture and mix it until just blended. Add 3 teaspoons of orange zest and lightly knead the dough. It is important to keep the kneading to a minimum, or the scones will be hard and as tough as nails.

Put the dough onto a lightly floured surface and roll it to about a 1-inch thickness. Cut the scones with a 2-inch round fluted cutter, as closely as possible to avoid wasting dough. Put them on the prepared baking sheet, about 1-inch apart.

In a small bowl, lightly beat the egg yolk and the remaining milk and brush this over the scone tops. In another bowl, mix the remaining sugar, coconut, and orange zest and sprinkle this evenly over the top of each scone. Bake the scones in the center of the oven until they have risen and are lightly browned, about 20 minutes. Cool the scones on a wire rack and then split them. Serve warm, with butter and honey.
