Reunion Island has some endemic species of palm of which the edible hearts are used in the local cuisine. Patience is required after planting, because it takes four to five years for the palm to produce the cabbage, or heart, inside its trunk.
Nowadays, it is harvested and marketed under the strict supervision of the ONF (National Forestry Office of France). Look out for the stamp on each palm heart, as their sale is regulated. Like any rare product, palm hearts are expensive. They are used in cooking mainly for big occasions.
