You will need:
1 C. all-purpose flour
a pinch of salt
2 eggs
4 T. melted butter
2/3 C. Milk and 2/3 C. water mixed together
Put the flour and salt in a bowl. Add the eggs and some of the milk and water, and whisk in the flour, a little at a time. Gradually pour the remaining milk and water into the mixture, whisking it until the ingredients are well mixed in. Add half the melted butter to the mixture and whisk it again. Brush the skillet with a little melted butter and heat until it sizzles. Pour in two tablespoonfuls of batter. Quickly tilt the pan from side to side until a thin layer of batter spreads across the bottom of the skillet. Cook the crepe for about a minute, then flip it over, cook it for 10 more seconds and slide it onto a warm plate.
