Rinse berries in a vinegar and water bath
Remember when we said don’t wash your produce until you intend to use it? Well, forget about that when it comes to berries! To extend the fridge-shelf life of berries, give then a quick dip in a vinegar solution (one-part vinegar to eight parts water) then drain them and put them away. The vinegar-water mixture helps kill any bacteria or spores that might turn berries into mush.
