Winged bean + Nance

The Winged bean (Psophocarpus tetragonolobus), also known as the Goa bean and Asparagus pea, Four-angled bean and Winged pea, is a tropical legume plant native to New Guinea. It grows abundantly in hot, humid equatorial countries, from the Philippines and Indonesia to India, Burma, Thailand and Sri Lanka. It does well in humid tropics with high rainfall. There are also varieties that can be grown in most areas of the U.S.. The winged bean plant grows as a vine with climbing stems and leaves, 3–4 m in height. It is an herbaceous perennial, but can be grown as an annual. It is generally taller and notably larger than the Common bean. The bean pod is typically 15–22 cm (6–9 in) long and has four wings with frilly edges running lengthwise. The skin is waxy and the flesh partially translucent in the young pods. When the pod is fully ripe, it turns an ash-brown color and splits open to release the seeds. The large flower is a pale blue. The beans themselves are similar to soybeans in both use and nutritional content (being 29.8% to 39% protein). The plant is one of the best nitrogen fixers with nodulation accomplished by the soil bacterium Rhizobium. Because of its ability to fix nitrogen from the atmosphere, the plant requires very little or no fertilizers. Being a tropical plant, it is sensitive to frost. Most plants will not flower if the day length is more than 12 hours, meaning they will not produce pods in most temperate zones, although day length neutral cultivars do exist. The seeds have a hard coat and it helps to soak them before planting to hasten germination. The plant grows very quickly, reaching a length of four meters in a few weeks.

Nance (also called craboo, kraabu, Savanna Serrette and Golden Spoon) is a species native to tropical America. It is valued for its small, sweet, yellow fruit, which are strongly scented. The fruits are eaten raw or cooked as dessert. In rural Panama, the dessert prepared with the addition of sugar and flour, known as pesada de nance, is quite popular. The fruits are also made into dulce de nance, a candy prepared with the fruit cooked in sugar and water. In Nicaragua (where the fruit is called nancite), it is a popular ingredient for several desserts, including raspados (mixed with ice). The fruits are often used to prepare carbonated beverages, flavor mezcal-based liqueurs, or make an oily, acidic, fermented beverage known as chicha, the standard term applied to assorted beer-like drinks made of fruits or maize. Nance is used to distill a rum-like liquor called crema de nance in Costa Rica. Mexico produces a licor de nanche. [Wikipedia]
