2In a medium-large bowl, stir together the flour, sugar, baking powder and salt. Grate in the butter, or cut it into bits and blend it in with a fork or your fingers, until it's mostly blended in, with bits the size of a pea still remaining.
3Add the milk and after a few strokes, add the berries and chocolate and stir just until the dough comes together. Pat it about an inch thick on a parchment-lined sheet and cut it into pieces - wedges or squares or rounds or just haphazard pieces. If you like, brush the tops with milk and sprinkle with sugar (coarse or not).
4Bake for 15-20 minutes, until deep golden. Eat warm. Makes about 8 scones.
