Well, I have given my one recipe for biscuits, and have seen the gamut of different ingredients, but here is the biscuit I personally bake at home and it is a little healthier, and it is the one my wife and I prefer.
2 cups of flour (wheat or white), blend in 3 tablespoons of baking powder, then blend in 1/3 cup of olive oil, and then 1 cup of milk. This is a very wet dough, and one has to use flour to work it, as it is sticky once out of the bowl.
Again preheat the oven to 430 degrees, grease the cast iron skillet with "olive oil" and you get a nicely browned, fluffy biscuit, that is also much healthier.
