Ever feel like berries just don't last that long when you bring them home, especially those just-picked from the farm? You're not alone. Berries have little germies on them that cause mold to form at an alarming rate (here's a more sciencey explanation).
To extend the fridge life of your berries, here's a simple trick. As soon as you bring them home, fill a clean sink basin (or a big bowl, if you must) with several inches of cool to lukewarm water. Add a half-cup of distilled white vinegar to the water. Then add in your berries. Gently swish them around with your hands and let them sit for a few minutes. Strain the berries and dry them (for firm berries like blueberries, strawberries, or blackberries, you can send them through a salad spinner. More delicate berries, like currants and raspberries, should be left on a towel to air dry). Place them in an airtight container and store in the fridge.
Or freeze them.
The vinegar disinfects the berries naturally and keeps bacteria from eating the soft flesh of the berries too quickly.
