To ripen firm kiwis, place them in room temperature, but away from heat or direct sunlight for a few days. To accelerate the process they can be placed in a paper bag with an apple, pear or banana. Ripe should hang on for one to two weeks. These fruits should be firm, glossy and bright. Lemons should be bright yellow, not greenish, and limes dark green.
Limes turn from green to yellow when they ripen, but the immature fruit has the best taste.
Lemons can be stored at room temperature for two weeks without refrigeration. Limes however, should be refrigerated immediately for they are more perishable. Both can be stored in plastic bags in the refrigerator crisper and kept up to six weeks. Mangoes Selection A ripe mango will yield to slight pressure when held between hands. The skin can either be yellow-orange or red, which will spread in area as the fruit ripens.
