trials with aluminum vs cast iron
I have been baking at my parents' home where I have access to one Le Creuset DO and one vintage aluminum DO. Bake after bake, the loaf baked in the aluminum DO has inferior rise and oven spring. Heat retention really does make a difference (at least that's what I have been finding). Both of these loaves are 50% whole grain and followed the exact same fermentation process, but the loaf on the right has superior spring.
