Maybe you already know this. It seems rather obvious, now that I've made the realization. But I'll share with you regardless. You know those plastic containers with the slits in them, the ones in which berries are sold? Well, if you turn them on their side -- vertically, that is -- in the refrigerator, the items within will last longer and are less likely to mold. Makes sense, right? Still, it had never occurred to me until I accidentally left some raspberries in that position and was shocked to discover that they were still edible several days later.
