Sift together the flour, baking powder, salt and curry powder.
Using your fingertips, rub the butter into the flour mixture until it resembles coarse crumbs.
Stir in ¾ of the cheese, ¾ of the chives and all of the parmesan.
Whisk together the milk and egg and then stir through the mixture with a blunt knife. Stir gently until the dough comes together, being careful not to overmix.
Turn onto a lightly floured surface. Pat together mixture with your hands and flatten until about 3cm thick.
Use a floured scone cutter to press out rounds.
Place the scones onto the baking tray, almost touching. Brush tops of scones with a little extra milk and sprinkle with remaining cheese and chives.
Bake for about 15 minutes or until a pale golden colour on top.
Allow to cool for a minute or two in the dish before turning out into a clean tea towel placed on a cooling rack. Wrap in the tea towel and serve warm with butter.
