Lupine + Purple mangosteen

Lupinus, commonly known as lupin or lupine (North America), is a genus of flowering plants in the legume family, Fabaceae. The genus includes over 200 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean. Seeds of various species of lupins have been used as a food for over 3000 years around the Mediterrranean (Gladstones, 1970) and for as much as 6000 years in the Andean highlands (Uauy et al., 1995), but never have they been accorded the same status as soybeans or dry peas and other pulse crops. The pearl lupin of the Andean highlands of South America, Lupinus mutabilis, known locally as tarwi or chocho, was extensively cultivated, but there seems to have been no conscious genetic improvement other than to select for larger and water-permeable seeds. Users soaked the seed in running water to remove most of the bitter alkaloids and then cooked or toasted the seeds to make them edible (Hill, 1977; Aguilera and Truer, 1978), or else boiled and dried them to make kirku (Uauy et al., 1995). However, Spanish domination led to a change in the eating habits of the indigenous peoples, and only recently has interest in using lupins as a food been renewed (Hill, 1977).

The purple mangosteen (Garcinia mangostana), colloquially known simply as mangosteen, is a tropical evergreen tree believed to have originated in the Sunda Islands and the Moluccas of Indonesia. It grows mainly in Southeast Asia, and also in tropical South American countries such as Colombia, in the state of Kerala in India and in Puerto Rico, where the tree has been introduced. The tree grows from 6 to 25 m (19.7 to 82.0 ft) tall. The fruit of the mangosteen is sweet and tangy, juicy, somewhat fibrous, with fluid-filled vesicles (like the flesh of citrus fruits), with an inedible, deep reddish-purple colored rind (exocarp) when ripe. In each fruit, the fragrant edible flesh that surrounds each seed is botanically endocarp, i.e., the inner layer of the ovary. Seeds are almond-shaped and sized.
