Put the flour and baking powder in a mixing bowl.
Rub in the butter with your fingertips until it resembles fine breadcrumbs.
Add the sugar, desiccated coconut and mango and mix really well. Beat the egg, add most of it to the mixture but leave a little aside to egg wash the scones at the end.
Add most of the coconut, leave aside about 50g for now. We do not want to use all the liquid straight away as we may not need it. How much you need depends on the moisture that is already in the flour and mango, and the temperature and moisture in your kitchen.
Bring the dough together into one piece, you can do this with a spatula or dough scraper or your hands. If it feels dry add more coconut milk. It should come together in one large piece and be a little sticky to touch but still firm. A stickier dough will make a softer scone and a dryer dough will make the end result dry too.
Empty the dough onto a floured countertop. Don't over-handle the dough.
Flatten the dough to about 2 inch thickness with the palm of your hand.
Using your scone cutter cut out the scones. Keep dipping the scone cutter in flour so it doesn't stick to the dough. When cutting the scones press and pull up in one swift movement, try not twist too much. This gives the scones a better rise.
Egg wash the scones with a pastry brush or your fingers. Then sprinkle with a little desiccated coconut.
Bake at 200 degrees celsius for about 14 minutes or until golden brown on top and hollow when you tap them.
