These fluffy pancakes get their rise from the magical combination of buttermilk, baking powder and baking soda. As the batter rests, baking powder reacts with the liquid ingredients to form bubbles that create fluffy pancakes, while the gluten in the flour relaxes to make them more tender. Baking soda provides extra lift, using the acid from the buttermilk to create a similar effect. Once the batter hits the heat, they rise one last time, resulting in perfectly tender pancakes that you can slather with your favorite toppings.
