Put the fruit in a bowl with the tea bag and cover with approximately 100ml (1/2 cup) of boiled water. Leave to soak for 15 minutes, then remove the tea bag, drain and thoroughly pat dry on kitchen towel.
Put a liner in the air fryer basket and lightly dust with flour.
In a bowl, mix the flour, sugar and baking powder.
Using the tips of your fingers, rub in the butter until you have an even crumb.
Slowly add the milk while mixing using a flat knife. The mixture should start to clump together.
Stir in the soaked fruit.
Tip the dough onto a floured surface and gather together, handling just enough to form into a disc that will fit in your air fryer basket. Don’t overwork the dough.
Cut the disc into eight equal triangles.
Lift the scones into the lined air fryer basket.
Brush the tops with milk.
Set the air fryer to 160C/320F and bake for 17 minutes until the scones are puffed and golden. Allow to cool before serving.
