Sift flour into a bowl. Add sugar and stir well. Add milk, butter and egg. Whisk until well combined.
Brush two small non-stick frying pans with a little of the extra melted butter. Heat over medium heat. Add 1/3 cup of mixture to each pan. Cook for 2 minutes, or until bubbles appear on the surface. Carefully turn over and cook fro 1 minute.
Transfer pancakes to a plate and wrap loosely in a clean tea towel to keep warm. Repeat with remaining batter, greasing pan between each batch. If you find the pan is getting too hot, reduce heat slightly.
Serve PANCAKES with lemon and sugar.
