What Does Buttermilk Do To Pancakes?
Buttermilk adds acidity and tanginess to pancakes, which helps to tenderize the gluten in the batter resulting in light, airy, and fluffy pancakes. It also activates the chemical leavening agents (baking powder and/or baking soda), making the pancakes rise higher. The acidity in buttermilk also helps to tenderize and moisten the pancakes and gives them a slightly tangy flavor profile.
