Reinhart barm question
I have looked at a number of previous questions about this an am still confused. I just made Peter Reinhart's barm (it's bubbly but hasn't puffed up the plastic yet). Once I use it, how do I refresh it? He says to double it, but how do I calculate that? Do I discard some? At one point he says to add a cup of flour and "some water." How much water? Help!
