Preheat the oven to 200C
Sift the flour and baking powder into a large baking bowl.
Rub the butter into the flour with your fingertips until the mixture resembles breadcrumbs.
Add the sugar, grated orange zest and dried cranberries and mix with a spoon or spatula.
Add 2 beaten eggs, the orange juice and enough milk to make a soft but not sticky dough. Add the milk a little at a time until you get the right consistency.
Dust your work surface with flour and pat the dough down evenly until it is about 2 cm high.
Cut out your scones and place on a non stick baking sheet or, if not non stick, line the baking sheet with parchment paper.
Reform the dough and cut until all of it is used.
Brush the tops of the scones with beaten egg and sprinkle with sugar.
Bake for 10-15 minutes at 200C.
Remove from the oven and transfer to a cooling rack.
When cooled split the scone and serve with butter and jam or, for special occasions, with jam and cream
