I make a large batch of this dry mixture base and keep it handy, sealed tightly in a container for a quick mix meal, simply having to add the wet ingredients when cooking. I then add the wet ingredients from above. The key to this recipe is to mix the white liquids together in a separate bowl, and the yellow ingredients together in a separate bowl, then folding these into the dry mix. So, in other words, mix egg whites with buttermilk, and mix egg yolks with butter, mixed in separate bowls, then folded into flour dry mixture. The equivalents are: 1/4 teaspoon baking soda per 1 cup flour 1/2 teaspoon baking powder per 1 cup flour 1/2 teaspoon kosher salt per 1 cup flour 1 teaspoon sugar per 1 cup flour
