Sift the flour into a bowl. Add the eggs and gradually beat in half the milk. Add the remaining milk and beat until smooth. Leave to stand for 10 minutes.
Lightly oil a frying pan and place over a moderate heat. Pour in just enough batter to cover the base of the pan when tilted from side to side.
Cook until the underside is golden, then turn and cook on the other side. Cool on a wire rack or plate. Repeat with the remaining batter.
