Heat the oven to 425 degrees. In a medium bowl, whisk the cake flour, salt, baking powder and 2 tablespoons of the sugar to combine.
Add the butter and combine with a pastry cutter, fork or fingers until pea sized crumbles form.
Add the egg and cream. If too dry, add 2 more T cream. It should still stick a little to your hands.
Turn the dough onto a lightly floured surface and knead a couple times, then press it into a ¾-inch-thick circle and cut into 2.5-inch rounds with a biscuit cutter.
Put the rounds on a silpat or parchment lined cookie sheet. Reshape the leftover dough and cut again. You should end up with 5 large scones.
Brush the top of each scone with a bit of cream and sprinkle with the 1 T of sugar.
Place scones in refrigerator for 15 minutes to chill the dough.
Bake for 12 minutes and serve immediately with clotted cream and preserves. Say Grace and enjoy!
