On the weekend I thought I would do some bread making; I feed my sourdough starter and then referred to a book I recently received – Ferment, Pickle Dry. This book has a few different sour dough recipes (among other useful things)- and a basic sough dough starter and production leaven guide. Has any one else ever used a production leaven? This is the first time I have come across this step in sour dough bread making – and it works a treat!
