Hi: I have just joined egullet and have just finished reading all the posts re: artisan bread. I have ordered the book and my questions may be addressed there, but I plan on making up a batch before the book arrives. I have two questions: What is a cloche? What do you cover your dough with in the fridge? I know that you are not to cover the container with an airtight cover, but do you use loosely drapped plastic wrap? A dish towel? If the latter, will it dehydrate the dough? Thanks for answering these questions.
