I was given some King Arthur SD starter for Christmas. After feeding and splitting and feeding again we made 'Rustic Sourdough Bread' from the KA website. It was fine - but the recipe called for yeast as well as the starter.
So I decided to try a San Francisco style sourdough per the "Bread Alone' book. I took the starter from the KA and basically turned it into the Chef per the Bread Alone book. Then made the Levain, then the Poolish, then the bread. It actually worked! The bread is great - even using brand x all purpose flour.
What has me a bit baffled though is that the San Fran sourdough recipe used 1 cup (8 oz) of the Levain to create the Poolish. There is plenty of Levain remaining to feed, maintain and bake again. However, using the Bread Alone book again to create a classic Pain Au Levain the recipe wants the full batch (18 oz) of Levain to make the bread.
I'm a little perplexed about how to manage the Chef/Levain so there is something to work with in a few days to bake again.
If I've followed the instructions correctly I should have created about 18 oz of levain following the BA method. 8 of which I used to make the San Francisco style bread. To the remaining Levain, the instructions are to add 1/2 c flour and 3/4c + 2 TBS water to return the Levain back to a chef to maintain.
Confused
Edit: The book says the procedure makes 18 oz. of Levain - however the total weight of flour and water following the BA methods is 30 oz. So I suspect I'll have 12 oz left to feed and maintain after using the 18 oz. I need a decent kitchen scale!
