Food writer Michael Ruhlman and his wife, Donna, put together a chart illustrating common dough and batter ratios to give a quick overview of how much flour, liquid, egg, fat or butter, and sugar goes into pasta, biscuits, pancakes, and more. Go to his blog to buy an 11-by-14-inch print of the chart for $20. He'll put up a PDF version later for those who want to print it at home.
