Mosambi citrus looks very much like a lime with an underlying yellow base and is about 7 centimeters in diameter. Some fruits will exhibit more yellow coloring and even the occasional orange hue. A nice, ripe Mosambi will be heavy for its size. The skin is full of essential oils; just one scratch on the surface of the peel will release an intense aroma. The taste of a Mosambi is generally sweet, though it can sometimes range from slightly tart to extremely sweet.
