Preheat the oven to 450°F (425°F if using a fan oven).

Sieve the flour and salt into a bowl.

Add butter and using fingertips rub into flour until you get a fine breadcrumb consistency.

Pour in milk (save a little bit to brush the top) and mix to a soft but not sticky dough (if too sticky add more flour).

On a floured surface, press dough to 3/4" thickness.

Use a 2 1/2" round cookie cutter and cut out 4 rounds.

Re-ball the dough and press down again, then cut 2 more rounds.

Put the rounds on a greased baking tray and brush the tops with the milk.

Place in the middle of the oven and bake for 7 to 10 minutes until the scones are well risen and golden.
