Shortbread for Christmas!

Here is my grandmas shortbread recipe, ideal for Christmas presents if the delicious bits last that long!
What you need!
4oz butter
2oz caster sugar, fine sugar , depending on where you come from.
6oz plain flour, Sieved.

How to make it, the fun starts here!
Heat the oven to 190C/375F/Gas 5. Beat the butter and the sugar together until pale.
Stir in the flour to get a smooth paste. Turn it out onto a work surface and gently roll it out until the paste is ½in thick.
Cut it into rounds or fingers and sprinkle with a little extra caster sugar. Put on a baking sheet and chill for 20 minutes, important. To be very posh you can prick the tops, gently with a fork to make little holes. not all the way through.
Bake in the oven for 15-20 minutes until pale golden. Cool on a wire rack.
Then dive into a shortbread heaven, unless your grandchildren get there first. I hasten to add it is not a bread, it is a flat Scottish sweet cake!
Best eaten with an accompaniment of a good malt whisky, whilst watching the Queens Christmas Speech at 3 o'clock on Christmas Day.
Kindest Regards From England.
