CLASSIC SCONES (eight to ten)
2 cups cake flour, more as needed
½ teaspoon salt
2 teaspoons baking powder
3 tablespoons sugar
5 tablespoons cold butter, cut into pieces
½ to ¾ cup heavy cream, more for brushing
1.Heat oven to 450*. Put flour, salt, baking powder and 2 tablespoons of the sugar into a food processor and pulse to combine. Add the butter and pulse until the mixture resembles cornmeal.
2. Add the egg and just enough cream to form a slightly sticky dough. If it’s too sticky, add a little flour, but very little; it should still stick a little to your hands.
3. Turn the dough onto a lightly floured surface and knead once or twice, then press it into a ¾ inch thick circle and cut into 2 inch rounds with a biscuit cutter or glass. Put the rounds in an ungreased baking sheet. Gently reshape the leftover dough and cut again. Brush the top of each scone with a little cream and sprinkle with a little of the remaining sugar.
4. Bake for 9 to 11 minutes, or until the scones are a beautiful golden brown. Serve immediately.
