Bright green Florida Persian limes are the popular market variety. Relatively large, seedless, and juicy, they enhance the flavor and visual appeal of drinks and dishes of almost any kind. Select limes that look fresh - not leathery or shrivelled at the stem end. Avoid ones with a brownish circle at the pointed end or any pitted areas, indicating rot or dryness. Refrigerate in a plastic bag for up to a week. Store at 55°F.
