Heat your oven to 450 degrees. Then combine the cake flour, baking soda, and salt in a medium sized bowl. Cut the butter into small cubes and add them to the flour mixture. Then use your hands to combine the flour and butter, mixing for a few minutes until small crumbs form. The texture will be similar to cornmeal.

Next add the egg and heavy cream, forming a sticky dough.

Quickly knead the dough on a floured surface, just to form a large ball of dough. Roll the dough out (or use your hands to stretch it out) until it is ¾ inch thick.

Use a biscuit cutter, or a glass, to cut the dough into circles 2-3 inches around.

Spread the scones out on a baking sheet covered with avsilpat a layer of parchment paper. Brush the scones with heavy cream and sprinkle some sugar on top.

Place the pan on the center rack of the oven and bake the scones for 9-11 minutes, until golden brown.

Serve with clotted cream and jam.
