Interesting. I guess I never left one cut in the fridge very long. My experience has been much like guac, the surface turns brown but if I cant ignore that (there is no taste difference, its in our heads mostly, with the surface browning we instinctively dont like it) I can scrape off that browned surface and underneath is green avocado. I dont think I've ever left a cut avocado in the fridge more than couple days though.

Awesome to hear you folks having them last un-cut in the fridge for weeks! good to know. I don think I've tried that, mine usually get eaten faster but I dont usually buy them by the sack or bag...I might now though!
