Put the flour, baking powder, salt and sugar into a bowl. Put the egg in the centre and mix until it is a smooth, thick batter. Gradually add the milk whilst mixing.
Grease a frying pan. Drop the mixture into the pan in spoonfuls. When bubbles begin to burst, turn over carefully and cook the second side. Cool in a folded cloth as steam as steam is needed to keep the scones soft. Serve hot or cold
