I don't think it's possible to make too many drop scones (or Scotch pancakes as they're also known). I once ate 54 at a sitting. It had to be a sitting: I couldn't stand afterwards. Makes 24 scones.
200g self-raising flour
Pinch of salt
Sift the flour and salt into a bowl. Add the eggs and milk, and beat until the mixture is smooth. Melt the butter in a small pan, add that to the batter and beat some more.
Grease a frying pan, then heat until almost smoking. Drop a tablespoonful of the batter into the pan. When holes begin to appear (about two minutes), flip it over and cook for another two minutes or so. Keep re-greasing the pan and griddling the scones until all the batter is used up. Oh, and eat as soon as possible.
