My sister Yvonne shared this tip on how to keep your raspberries and strawberries fresher for longer and I just had to share. It may be a while before we are picking our own raspberries in Ontario even with this crazy warm weather, but as the berries start pouring into your grocery stores this is a good tip to be aware of - especially when you are paying $4 for a tiny little handful of the delicious red things!
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.
