I love to eat berries when they are in season. Fresh berries on cereal, in yogurt, shortcake or just by the handful. But nothing is worse than buying berries and the next day you find mold on them already. Here's a helpful tip that will extend the life of your berries without freezing them. Wash them with vinegar.
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 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. Raspberries will last a week or more, and strawberries go almost two weeks without getting moldy and soft. So go forth and stock up on those pricey little nutritious gems, knowing they'll stay fresh as long as it takes you to eat them.
