Mix the 450 grams Plain Flour with 7½ tsp Baking Powder. (If using UK self-raising flour, only add 2 tsp baking powder). Then mix in the softened 75 grams Butter (unsalted) & toss to coat. 'Cut the butter' into the flour with a pastry cutter (pastry blender) until like rough large breadcrumbs. Should only take about 1 minute to do, or you can use 2 butter knives or your hands. Lift the mixture between your fingers, and run your thumb across the fingertips. Regularly lift more mixture up and work across the bowl. See video for reference. DO NOT USE A FOOD PROCESSOR.
Add in the 50 grams Caster Sugar (extra/super fine sugar & should not be omitted) & mix till combined. Leave to the side and crack 2 Med-Large Eggs into a jug, before adding in enough of 240 ml Milk to take it to the 300ml (10 fl oz, 1¼ cup level). Give a good whisk to combine. Reserve 2 tsbp in a small dish for egg-washing later.
Make a well in the centre of the flour mixture & add half of the egg/milk mixture. Mix in before using a spoon or spatula to push down on the mixture, making the flour take on as much liquid as possible, before adding anymore liquid. Add only little drops from here on, till a dough starts to come together and is only a little bit sticky. You can use your hands to bring it together & feel the texture, before forming into a disc. **Note you might not need all the egg/milk mixture or need a tiny bit more.
Flour a work area (or use the bottom of the bowl if large enough), and open out the dough with your knuckles or palms. Add ⅓ - ½ of the chopped 80 grams Dried Cranberries on top of the surface of the dough, followed by 10 drops of the Foodie Flavours Mango Extract. Fold over the ends of the dough, into the centre, then turn the dough over and open out again by hand. Sprinkle the rest of the cranberries on top, as well as 10 more drops of the extract & repeat the folding over motion. This should incorporate the cranberries evenly.
Flour a work area or baking/parchment paper. Form the dough into a disc & open out to at least 1" (2½ cm) thick by using your palms (DO NOT USE A ROLLING PIN).
Dip the cookie cutter (straight edge side), into some flour before cutting out the scones. Try for as many as you can get form this first round. 5-6 scones is normal. Any scones that lift up, shake onto a prepared, paper-lined baking tray (baking sheet) if using a regular oven or larger air fryer. Or onto the prepared basket air fryer rack. TRY NOT TO TOUCH THE SIDES OF THE SCONES. Any scones that don't lift up can be released at the end by pulling away the excess dough & transferring with a spatula.
Once you have your scones on the air fryer rack (on top of small piece of paper), very carefully brush the reserved egg-wash on top of the scones, making sure not to let it drip down the sides. **TOP TIP - tap your brush of excess liquid, then brush from the centre of the top of the scone, working your way out, to reduce chances of drips.
