The best Dutch oven for Sourdough bread will have the following:
– Heavy base and lid– Solid cast iron, ideally including the handles so it can handle the highest heat– Fit the shape and size of your loaf– Well crafted seal between the lid and base so as not to let any heat and/or steam escape
A Dutch oven will give the best oven spring (rise in the oven).Your sourdough will have the best crust (thin and crispy). Your sourdough will have the best crumb (open holes and airy texture).
