One of my real kitchen pet peeves is - "What on EARTH am I supposed to do with this half an onion??" Inevitably, I throw it into a baggie. And then you know what happens next - everything from the watermelon slices to the butter ends up with a certain onion-ish taste. Not terribly appetizing.
That's why these onion savers are true brilliance in my books! They seal up ultra tight, giving you lovely fresh onions inside, but no lingering odors to drift in the direction of any of the other culinary delights in your refrigerator!
Hurrah for the onion saver! Fantastic design, too.
