Drying store bought bread for stuffing I am drying a loaf of sourdough on my counter. There is a lot of it, so I will need to store some of the dried cubes. My question is, how do I store it and how will I know if it is no longer good to cook with? Also, is it better to just put it in the oven to dry it rather than on the counter?
There are two types of bread for stuffing.  If you're aiming for the dry type, a very low oven would be better.

If you have room in your freezer, that would be a good place to store the bread you're planning to use later to make stuffing.
