Making the perfect hotcake all depends on how you mix the batter.
Remember that lumps are ok, and you want to see that in your mix. Stir your batter until the dry and wet ingredients are just incorporated, leaving a bit of flour streaks, and all those beautiful lumps.
Overmixing results in gluten developing from the flour in your batter, making your hotcakes tough n’ chewy instead of fluffy n’ tasty.
