Place the flour, sugar and salt in a large bowl. Whisk in the eggs and 3/4 cup (180ml) of the milk until smooth. Gradually whisk in the remaining milk. Cover and stand the batter at room temperature for about 1 hour.

Heat a 20cm crepe pan (or frying pan); brush with a little of the butter. Pour about 2 tablespoons of the batter into the pan, tilting pan so batter coats the base evenly. Cook, loosening edge with a spatula until crepe is browned lightly underneath. Turn crepe and cook until browned on other side. Transfer crepe to a plate or ovenproof dish; cover to keep warm. Repeat with remaining butter and batter, stacking crepes on a plate.

Crepes can be served folded in half or quarters, or filled and rolled and served with desired toppings, They can also be dusted with sifted icing sugar and placed under a hot grill to brown lightly if desired.
