Mamoncillo, or Spanish limes, grow in clusters of 12 or more fruits at the end of the branches of large green, leafy trees.
Individual branches are removed and the fruits are commonly sold in clusters. The small fruits measure 3 to 4 centimeters in diameter and are almost perfectly round.
The thin skin is smooth, tough, and leathery with the occasional protrusion opposite the stem end. The pulp has a gelatinous and glistening appearance, similar to that of a lychee.
The flesh is referred to as the “aril” and can range in color from salmon-orange to pale yellow. It clings to a large white seed (sometimes two) at the center of the fruit.
When Mamoncillo are ripe, the pulp is sweetly acidic and can be compared to a cross between a lime and a lychee.
