delaying moldy bread
I've been using Bread Bags (variation on Green Bags, not sure which came first) with some reasonable success.  I'm sure there are other brands and sites to buy them from.  I normally just grab them at the grocery store/BB&amp;B.  I only remember the details from the green bags, but they have lining that absorbs chemicals that are released by vegetables to slow down decay. I assume the bread bags use something similar, helping to control humidity as well.

We also slice then freeze bread, getting out slices as needed, throwing them in toaster to reheat.
