Secret #2: Ripen these foods on the counter and then refrigerate: AVOCADOS, KIWI, STONE FRUITS (peaches, plums, nectarines, etc.) and use within a few days.
BANANAS should also be kept at room temperature. If refrigerated, peels will turn black, but it doesn’t really affect quality or taste. (Very ripe bananas can be frozen, un-peeled, until later. To use, simply peel the frozen bananas under warm water and add them to smoothies or mash for breads and other baked goods.)
