I want to make the Chocolate-Cherry Pecan Bread in King Arthur's August Catalog. The directions are for baking it in a Dutch Oven like the bread from The New York Times last November. I would like to bake it in 8 1-pint casseroles instead. The baking time for large loaf is 20 minutes with the lid on and then 30 to 40 minutes with the lid off. Anyone have a guess at what time I should remove the lid on the small casseroles? (I will use thermometer to test for removal time.)
