I present to you an amazing discovery!
I bought this loaf of bread so long ago, I can't remember. It's been at least a month. Probably more. It has yet to mold.
Just last week, Spouse was comfortably eating peanut butter sandwiches with slices of this bread. Month-old bread.
In the background, is it's replacement. I am retiring the old miracle bread tonight.
For only being 45 calories (per slice) it actually was pretty good.
Maybe that's why it didn't mold or "go bad." It's mostly made out of air.
