Combine flour, sugar and salt in a bowl. Make a well in the center of the flour and add the milk and egg. Beat well to combine.
Heat a lightly oiled griddle or frying pan over medium high heat. Pour the batter onto the griddle, using approximately 1/4 cup for each crepe. Tilt the pan with a circular motion so that the batter coats the surface evenly.
Cook the crepe for about 2 minutes, until the bottom is light brown. Loosen with a spatula, turn and cook the other side. Serve hot.
