The other day I was heating up some leftover prime rib for lunch and I thought to myself "You know, that grated horseradish in the fridge would be the berries on this." So I pulled out the jar, but noticed that the use-by date thereon was September of '08.
Hm. How funky does this stuff get as doomsday approaches? Without putting a lot of thought into the matter, I uncapped it and took a big whiff.
Which was kind of pointless when you think about it, because even freshly grated horseradish smells like a stale onion in an old sweat sock. How can you tell when it's gone funky?
FWIW, this stuff was still just fine. Yum!
