The recipe for plain scones goes through the whole process in more detail and is a good read for the beginner baker.
Scones are really simple to make and difficult to go wrong. Unless you’re selling them for one reason or another don’t roll them out and use a cutter just ease the mix into a squarish shape and cut with a sharp knife or dough scraper.
Sieve 8 ounces of self raising flour into a bowl with1/4 teaspoon of salt, 1 teaspoon of baking powder and a teaspoon of English mustard powder.
Rub in 2 ounces of butter until the mix looks like fine breadcrumbs and mix in 3 ounces of grated mature cheddar cheese.
Mix with 125 ml or so of cold milk and turn out on to a floured board and shape into a rectangle. Cut into squares or triangles, brush with milk and sprinkle fresh chives, Italian hard grated cheese, paprika or chilli powder on top.
Bake 180/190 for 8 – 10 minutes in the centre of the oven. Cool on a rack, best eaten warm.
