mdmc, I've read the same thing.
CC, you don't notice a different taste & texture in your refrigerated potatoes? I've heard the cold temp converts the starch into sugar, making them taste sweet.
We don't eat many potatoes, so there's not really a storage issue here. I do keep my onions in a basket on top of the fridge ... shallots too ... which is supposedly a no-no because of the warm temp, but I've never had a problem with sprouting ... maybe because they don't sit there long enough.
