Bean sprouts are a common ingredient in stir-fry recipes, but they don't seem to last very long in my fridge.
How can I keep bean sprouts fresh for the maximum amount of time?
Looks like ehow has the best reference guide thus far to storing bean sprouts
After purchasing Bean Sprouts should be stored and washed after purchasing in growing. The article indicates that the best methods for storage are the following:
It also mentions in the article to just grow them to provide the best freshness.
Apparently the shelf life of beansprouts should only be stored up to 3 days
I've been keeping them in a jar in the crisper section of the refrigerator, and they seem to be still fairly crunchy going on two weeks. I found a jar of them last week that'd I'd forgotten from the previous week and they were in much better shape than the ones bought nine days later but for which I didn't have an available jar.
I don't rinse mine until right before I use them; most of my vegetables seem to keep longer that way (presumably because they'd be nearly impossible to dry thoroughly).
Edited to clarify: I always cover everything thoroughly, so the newer sprouts were wrapped in wax paper, then aluminum foil.
