Preheat your oven to 200 C/400F/Gas Mark 6.
Put 225 grams flour, 1 gram salt into a large mixing bowl or food processor.
Tip and then rub 50 grams cold butter into the flour with your fingertips or whizz with the flour in the food processor for 20 seconds or so until you are looking at fine breadcrumbs in your bowl.
If using a food processor then tip the fine rubble into a large mixing bowl.
Tip the 120 grams of mature cheddar cheese and six sliced/snipped spring onions in and then pour in the 150 mls milk.
Using a wide bladed blunt knife or similar stir the milk into the mixture until you get a shaggy dough.
Now is the time to get your hands in and squish the dough into a smoother dough ball still in the bowl. Tip it out onto a very lightly floured surface.
Using your hands and/or a rolling pin very gently shape the dough to 3.5 cm thick. It will be a relatively small shape. Using a 6 cm cutter or similar cut out the scones. Dip your cutter into flour in between cutting out rounds so as to stop the dough sticking.
Reshape the left overs and gently repeat until you run out. If the last is not enough to fashion a whole scone then just use your hands to make a scone shape. That one is yours......cooks perks.
Brush with beaten egg wash and bake for approx 15 minutes
Cool on a wire rack a little before slicing open warm and slathering with butter.
