Tip all the ingredients into the bowl of a food processor and mix in bursts until the ingredients bind together, taking care not to over-mix it or the cherries will be too finely chopped.
Alternatively, tip the flour and baking powder into a bowl, and rub in the butter.
Roughly chop the cherries and add them with the other ingredients, mixing with a round-bladed knife until a dough is formed.
Roll dough out on a lightly-floured surface to about 2cm (3/4in) thick and use cutter to stamp out scones.
Re-roll trimmings and cut out more scones until dough is used up.
Place them on the baking sheet.
Brush the glaze over the top of the scones, then bake them in the centre of the oven at Gas 7/220°C/230°F for about 15-18 mins, or until they have risen and are a light golden colour.
