Notes
How to get fluffy pancakes:
Don't over mix the pancake batter. Too much mixing causes the gluten protein to bond tightly with other gluten proteins which makes for a tough pancake.
Flip the pancakes when tiny bubbles form and the edges of the pancake look slightly dry.
Only flip the pancake once and don't press down on it with the spatula.
