Tartine bread failures
I recently got so enthused with my new Tartine bread book and eagerly started baking. My first attempt gave me 2 delicious tasting, but flat pancake loaves. The second attempt rose a little more but still flat. Then for the third attempt, since I had to bake at a friends place that day, I baked in loaf tins instead of the dutch oven. These rose beautifully, though the crumb wasn't full of huge air bubbles like I wanted. And to get through the steam problem, I simply had a tray on the bottom rack of the oven and poured some water into it a couple times. This seemed to work well.
My first attempts with the dutch oven proved that the steaming wasn't sufficient as when I lifted the lid after the first 2o minutes of baking the crust was already forming, preventing the loaf from rising to its ful potential. So I decided I wanted to do what I did when I baked in the loaf tins and pour water into a tray at the bottom of the oven to create steam.
I really like the rustic free-formed loaves so instead of baking in the tins I wanted to bake on my oven stone. However, my fourth and fifth attempt didn't turn out so well. The whole process seems to go very very well and pretty much look exactly as the book displays, that is, right up until I have to turn the loaf out to bake. I have been trying to turn the loaf out gently onto a sheet of parchment on a cutting board and then taking the board to the oven stone and sliding the loaf onto it followed quickly by a cup of water under it to create steam.
The problem is, and always has been when I've done this, is that when I turn the loaf out it totally has no tension and basically blobs out like a flat pancake. In the book, it looks as though it should hold its shape a bit more. And it is so soft and fragile that I can not really score it, even with brand new sharp razor blades.
I have tried the final rise at warmish room temp (25-27 celcius) for everywhere between 2 and 4 hours and the results have been the same - a blob.
I'm not sure where the problem is. Am I overproofing? Underproofing? Not building enough tension in preshape or final shaping?
Any help is much appreciated!
