The fruits, which look like small mandarins, are very acid. The juice can be used like lemon juice to season dishes, or made into a refreshing drink. Other uses of the juice include acting as a marinade or a dip. It will also arrest browning in bananas, as lemon juice does; and is good to squeeze over papaya for breakfast, or over pansit (see noodles of Asia). In addition, the fruits can be pickled. The preserved peel is often used as a flavouring.
