Hi again guys.
I posted here before and asked for your help- see link (http://www.thefreshloaf.com/node/35978/tartine-sourdough-help-me-understand-what-i-did-wrong)
Sadly, my loafs are not rising as they should and that despite using the book's exact recipe and instructions. I measure the temperature and fold properly. However, I don't use a Dutch oven and I can't buy one right now.
