Porridge Sourdough (Based on BBA Basic SD)
I cooked up some of the Bob's Red Mill 10 Grain Wholegrain Cereal and used it in the preferment instead of the main dough.
Preferment 1st Build:
25g of ripe starter
50g of cooked cereal
50g of water
Preferment 2nd Build:
150g of cooked whole grain
50g of white whole wheat
200g of water
