My first mother-in-law gave me this recipe many years ago
2 cups Self Raising Flour 2 tablesp Icing Sugar
2 tablesp Margarine pinch Salt 1 1/2 - 2 cups Milk
I always sift the flour,salt & icing sugar about 5-6 times
Rub through the Margarine until biscuit crumb consistency
Add milk & mix well through ( I use a knife)
The mixture should be a bit sticky
Place on a floured board & knead until the outside are no longer sticky & inside it is not too dry
Cut into squares or use a flour dipped cutter
Cook in a moderate oven for about 15 minutes or until brown on top
Allow to cool while being wrapped in a teatowel
Great with jam & cream
You can also add chopped dates or sultanas to change the taste
Fail safe recipe
