I looked for an easy batter and found one that used just a few ingredients. Equal parts AP flour and liquid, salt, and baking powder. I bought a bag of self rising flour by mistake so I tried that and left out the baking powder. I am still trying to work down a cannister of powdered milk so I used that to make milk for the batter. It seemed too thick so I added more water. The batter worked OK. I wonder if following the recipe more closely would work. I do note that the comments indicate that the recipe amount of baking powder was too much and most reduced it by at least half.
