I posted this in another cooks post as a reply as I was leaving work and on the way home, I realized that was the wrong thing to do so I removed it and started my own thread, sorry for being thoughtless. Anyway, this is what I posted.... I go to Costco all the time and buy large cuts but I take them home dress them , portionize them, vacuum seal them and then freeze. Could I keep a full strip in my fridge and just slice off a steak or two as needed? I see at Fairway Market, they have slabs aging in what appears to be some sort of glass enclosed storage case. I do not know if this thing is refrigerated or not. It doesn't look like a refrigerator. Anyway, how long can you keep a slab laying around and under what conditions. Red.
