The tree and fruit of Phyllanthus acidus. The intermediate sized tree produces small, flattened, multi-lobed, berries with a high acid content. The tart yellow berries are edible raw, but most often stewed with sugar, ginger and other spices.
My friend brought me about 35 pounds of grosellas (caribbean goose berries) and my wife is making " dulce de grosellas". They are boiled with sugar and turned red,it takes about an hour and you have turned a sour fruit into a sweet,delicious treat.
