The Key lime, named ‘’Citron Galet’’ in Reunion Island, originally comes from South East Asia. It takes its English name from the American Keys archipelago located in Florida. It was probably introduced in Reunion Island, before the presence of Europeans, by sailors from Southern India or even from Java, Indonesia.
Measuring between 2.5 and 5 cm in diameter, the Key lime is picked green and gradually become pale yellow at maturity. Pulp is greenish yellow and it is grown all year long following flowering cycles. Key lime tastes tangy, sweet, slightly iodized but not spicy. In Reunion Island, the juice and zest of key lime are close friends of rum and sugar, and it can also be used in local cocktails such as ti-punch.
Like its citrus siblings, Key lime is excellent source of vitamin C and a proven antiseptic - antimicrobial agent. On top of containing calcium and sodium, the Key lime also contains phosphorus, copper and manganese which enhance the action of vitamins, promote oxidative reductions and stimulate heart and neurons.
