Weigh 150 g (1 ¼ cups) self-raising flour into a medium bowl, add ½ tsp baking powder and a pinch of salt. Add 40 g (3 tbsp) butter cut into small cubes.
Rub the butter through the flour with gentle movements until the mixture looks like fine breadcrumbs. OR use a food processor to combine the ingredients.
Add the 25 grams of caster (superfine) sugar and 40 g of glace (candied) cherries cut into quarters, and stir through the mixture.
Pre heat the air fryer.
Add 80 ml milk to the mixture and use the blunt knife to stir the mixture together, just enough to combine ( you may need a little less or a little more milk) Then turn the mixture out onto a floured surface.
Knead the dough quickly and lightly, then pat the dough out into a flat disk about 2.5 cm (1 in ) deep.
Use a plain 6 cm (2½ in) cutter to cut out four scones. Pat the dough back together gently so you can use all the dough. You may have a little dough left over but not enough for another full size scone.
Use a pastry brush to brush the tops of the scones with a little extra milk.
Put a piece of baking parchment in the base of your air fryer and place four scones, spread apart, onto the baking parchment.
Close the air fryer and set to 185C (365F). Bake the scones for 11 minutes. After 11 minutes check the bottom of the scones, if they seem a little pale, turn the scones bottom side up and bake for a further 2 minutes.
Remove from the air fryer and cool for at least 5 minutes on a cooling rack.
Serve the scones split with butter and jam. Add clotted cream for an extra treat.
