Don’t be tempted, as we were, to line the air fryer tray with baking paper, we tried it out for you and can confirm it will burn.
125g plain flour
1 ½ tsp baking powder
¼ tsp salt
Pinch of cracked pepper
100g cheese, grated
½ cup milk
First grate the butter into a bowl then put that back into the fridge (you want to keep everything cold).
In a second bowl sift the flour, salt and baking powder, then add the pepper. Rub the chilled butter into the flour mix with your fingertips until in resembles fine bread crumbs. Mix through the grated cheese. At this point pre-heat your Instant Pot Air Fryer using the bake function set to 180C - it only takes a few minutes to pre-heat.
Back to your scone mix, add milk and use two fingers to mix until “just” combined (do not over mix). On a board or your bench lightly mould the dough into a rectangle (again trying not to overmix) and cut into either 12 squares or, using a round cutter, into circles. Brush with milk and lay on the air fryer tray, top with extra cheese and close the door. Bake for 9 minutes before cooling slightly then slathering with butter.
