Averrhoa bilimbi )is an important food source in Asia, Africa and in one small region of Brazil, the southern coast of the state of Bahia. It is virtually unknown elsewhere in Brazil, but plays an important role in the cuisine of southern Bahia, where it is known as most commonly as biri-biri but also as bilimbi, or caramboleira amarela.
Bilimbi is a close relative of the carambola or star fruit and shares a high level of acidity with that plant. It is used in Asia to provide acidity to curries and sauces, and it the major ingredient in many jams, relishes, pickles and chutneys. It also has medicinal uses, and with its high acidity is used in cleaning and bleaching solutions. In Malaysia is is even used to clean the traditional dagger, the kris.
The fruits of the bilimbi tree are about the size and shape of a small zucchini and are a bright green. They can be eaten raw, but are extremely sour due to their acidity and are usually cooked to reduce acidity. In Bahia they are used to make both savory and sweet conserves, and the presence of these on a table is a distinctive trait of the traditional regional cuisine.
Bilimbi can be successfully grown in the USA, though only in tropical regions or Florida and Hawaii. Seeds are available online at Tropilab, Inc.
