Select eggplant that are ripe but not too ripe. When pressed, the skin of a perfectly ripe should indent but spring back. If the eggplant is too hard to indent, it is under-ripe, and if the mark does not spring back the eggplant is overripe. If too young, an eggplant will look and taste ?green? and have little eggplant flavor. Past its prime it will have a spongy interior and bitter flavor. Eggplants bruise easily when transported. Store them in a cool spot at about 50 degrees and use as soon as possible. Refrigerator storage causes some of the bitterness sometimes experienced with eggplant. Young or small eggplants that have a thin skin may be cooked without peeling.
