I never, ever keep them in the fridge, though. And in a pinch, there is one brand of key lime juice you can get away with... I'll find it at the store and pass it along if anyone is planning key lime pie martinis (which are fabulous, by the way, but cream-based)...

If your herbs are aging too fast (like your mint for the mojitos) consider freezing them in water and defrosting as needed.
