My younger son and I absolutely adore stale marshmallows as a treat. They're tough, yet chewy and sweet.
So six months ago I bought a bag of gigantic, king-sized marshmallows, slit it open, and left it in the back of the pantry, just to prepare for our next visit to his place. I hauled them out tonight to pack 'em up, since we'll be going to visit him and his family soon.
My, oh my, they are good (of course I had to "sample" one). It will require considerable will power not to eat them all before we go.
