Mix flour and bran.

Add sugar, salt, sour cream.

Slowly pour in the whey, stirring. It took me about a Cup, depending on the humidity of the flour and the fat content of the cream may take more or less. Focus on consistency: the dough should be like thick cream, or on pancakes. I have this photo doesn't really work, but you can understand.

Now add the baking powder (I replaced it with pinch of baking soda and citric acid). Bake the loaves in a preheated, slightly greased with vegetable oil the waffle iron for 5 minutes. I got one of these products 5 standard waffle "flowers". Since the waffle iron I have is not for thin wafers, bread was not crispy but still very tasty. What happens in the waffle iron for thin wafers, I am myself very interested :). I would be glad if someone will share their experiences.
