I frequently make scones, and freeze some, using an old recipe.
1lb self raising flour
teaspoon baking powder
3 teaspoons sugar
couple pinch salt
4 ozs soft margarine
milk
about 250 grams natural yogurt
Rub the margarine into the sifted flour and baking powder, add sugar and salt. Add natural yogurt, and enough milk to make a soft consistency. Put onto floured board, and handle as little as possible. Roll out, or push out with your hands and cut into rounds about 1" thick. .
Place on baking tray,brush with milk and cook in oven Gas 6-7 for about 12 mins or until golden and cooked.
Sultanas can be added into the flour mix if wanted.
