Baking soda or baking powder? The review by the author confuses a little.

Very delicious

I've also made these and LOVE them!

I pour the milk into the measuring cup, then pour in the lemon juice and egg and mix them all together then add them to the dry ingredients. It's the chemical reaction from the lemon juice and baking soda that makes these so light and fluffy, if you don't have lemon juice, you could probably substitute apple cider vinegar, or even use buttermilk instead of the milk and lemon juice. Don't over mix the batter. When cooking, don't flip from side to side, just flip once per side otherwise the pancakes will become tough. [I posted this recipe.]
