Preheat the oven to 400F.

In a medium bowl, stir together the flour, sugar, baking powder and salt. If you like, add a handful of grated sharp cheese, some fresh or frozen berries, chocolate chunks or other additions. Add the cream and stir just until the dough comes together. On a lightly floured surface, knead the dough a few times, then pat into a circle about an inch thick.

Cut into wedges and transfer onto a parchment-lined baking sheet; if you like, brush the tops with milk or extra cream and sprinkle with coarse sugar. Bake for 15-20 minutes, or until golden. Serve warm.
