Received this worthy tip in an email this morning, thought I would share as most everyone loves berries.

The key to preventing moldy berries? Vinegar!

Berries, particularly super-fresh berries, are just wonderful, aren't they?

But they're also kind of delicate. Raspberries in particular seem like they can mold before you even get them home from the market. There's nothing more tragic than paying $4 for a pint of local raspberries, only to look in the fridge the next day and find that fuzzy mold growing on their insides.
Well, with fresh berries just starting to hit farmers markets, you can tell that we Foodlush writers have berries, and how to keep them fresh, on the brain this week! First Jonna shared this excellent tip on how to salvage berries that are starting to lose their luster. Now I'm here to share a tip on how to prevent them from getting there in the first place:
Wash them with vinegar.
A friend of mine shared this tip with me a few weeks ago, and it really, really works. When you get your berries home, prepare a mixture of one part vinegar (white or apple cider probably work best) and ten parts water. Dump the berries into the mixture and swirl around. Drain, rinse if you want (though the mixture is so diluted I find you can't taste the vinegar,) and pop in the fridge.
The vinegar kills any mold spores and other bacteria that might be on the surface of the fruit, and voila! Raspberries will last a week or more, and I've had strawberries go almost two weeks without getting moldy and soft. So go forth and stock up on those pricey little gems, knowing they'll stay fresh as long as it takes you to eat them.
