Combine flour, egg, milk and salt (if using) in large measuring cup or bowl.
To save on dishes I use the same measuring cup that I use to measure the milk.
Let mixture sit for 30 minutes or longer.
Heat skillet over med high heat and Melt 1 TB butter or margarine.
Pour in 2-3 TB of pancake mixture in hot skillet for each pancake (pancakes should be small and thin).
Cook until small bubbles form, turn and cook other side.
These cook very quickly.
Serve with butter and maple syrup.
