So the experimentation continues. This time I started the bread in a cold oven in a dutch oven. It produced a light bake and whilst this loaf was baking I held back the other loaf in the fridge. Both doughs weighed exactly the same. Then I placed the second loaf into the hot oven on a tray. The next experiment will be cooking the second loaf in the preheated dutch oven.
And the bake itself produced a lovely soft loaf, it was delightful, I really enjoyed this loaf. I think there may be something in this idea for the home baker.
