Description: The fruit of the Nagami kumquat tree grow in clusters. The fruits themselves are oval with a smooth pebbled surface. They ripen within a month from green to brilliant orange. Once mature, the fruit can reach up to 2 inches in length. Unlike citruses, the entire fruit is edible, although the few seeds buried in the flesh are recommended to be spared. The peel is where the true citrus sweetness lies in both aromatics and flavor. The flesh delivers a tart and juicy contrast, and if eaten whole, makes for a perfectly sweet-tart mouthful. Before disposing of or simply eating, consider saving the seeds, as they are a source of natural pectin.
