But how do they really taste? I’ve eaten everything from one month old MREs to 11 year old MREs. While I haven’t been brave enough to try the 10 year old Omlette with Ham, I have tried the 11 year old corned beef hash and the 11 year old ham slice/potatoes au gratin. They were both perfectly yummy (if you like those kinds of foods). The ham slice was nice and tender – more like Hormel’s Tender Chunk Ham. The corned beef hash was like any can of corned beef hash I’ve ever eaten. All the other MRE entrees I’ve tried – from 1994, 1998, 2000, 2001, 2002 have all been good – no sort of off-flavors or bad tastes.
