Cheddar-Chive Scones

Preheat oven to 400 °F. Whisk together flour, baking powder, sugar, and salt. Add chives and Cheddar, tossing to combine. Stir in cream with a fork until a sticky dough forms. Turn dough out onto a lightly floured surface and knead 8 times with floured hands. Halve dough and form each half into a 7-inch round. Brush tops of rounds with additional cream and cut each into 8 wedges. Arrange wedges about 1/2 inch apart on an ungreased large baking sheet and bake in middle of oven until golden brown, about 20 minutes. Cool on a rack.
