There is a very specific way to make scones, and I'm going to break it down step by step here.
Firstly - you need to put the cold butter into flour and mix it in quickly with your fingers. This is similar to how you would make pastry. Use the tips of your fingers and lightly rub in the butter until there are no large lumps of butter left in the bowl.
Next, stir in the sugar and salt.
As the mixture starts to form a dough, rub some flour on your hands and then finish mixing it all in with your hands, to bring the dough together into a ball. (Kids love doing this bit!)
Now turn the dough out onto a floured surface, and use a lightly floured rolling pin to roll it out to around 1 inch thick.
Once you have cut out as many shapes as you can get from the dough, bring it all together again and roll it out again to cut some more shapes. Keep doing this until you have used up all the dough. Now you just need to put the scones in a pre-heated oven and bake them for around 12 minutes.
