Calamondin orange🍊 (also known as Filipino LIme, Calamondin Lime, or Calamondino) is a small citrus tree that is a naturally occuring hybrid of mandarins and kumquats. The rind is green when ripe and the flesh is orange. Delicious tart, lime-flavored fruits reach an inch in diameter and can be used in jams and jellies or eaten right off the tree -- peel and all!
