1 - Add flour, salt & butter to a bowl, rub the butter into the mixture until it looks like breadcrumbs, then add the sugar.
2- Beat the egg and 2tbs of the buttermilk in a separate jug and gradually mix this into the bowl. Work the dough until it starts coming together, then finish mixing by hand. You can add extra flour if too sticky, or extra buttermilk if it is too dry.
2 - Roll the dough on a floured surface and roll to at least 1 inch thickness. Cut into rounds with your pastry cutter and place on baking tray. Brush the tops with a little buttermilk and place in the oven
at gas 7 until golden brown (have a peek at 10mins).
Remove from the oven and leave to cool on a rack.
Serve with lots of jam - strawberry or raspberry are delicious and clotted or whipped cream.
