Woo what an ingenious invention! I've never heard of the wonderbag. I read the article because I couldn't understand how you could cook in a cloth bag? I was surprised, I imagine it was a woman who invented it. It is always from needs that great inventions arise! Your bread looks very good. How long did you leave it in the wonderbag?
Thank you so much for your nice comments, I let it prove about 1 - 2 hours in the Wonderbag and then baked it in the oven.
