Tea leaf willow + Winged bean

Salix pulchra is a species of flowering plant in the willow family, known by the common names diamondleaf willow, tealeaf willow, and thin red willow. It is native to northern North America, where it occurs in Alaska, Yukon, the Northwest Territories, and Nunavut. The species is also found in northern British Columbia, and occurs in Russia. This willow is an erect, deciduous shrub growing up to 4.6 m tall, but usually remaining smaller, especially in the Arctic and in alpine climates. Along with S. richardsonii and S. alaxensis, it is one of the tallest growing willows in the Canadian Arctic Archipelago. The species is dioecious, with male and female reproductive parts occurring on separate individuals. The inflorescence is a catkin. The catkins grow before the leaves appear in the spring. The leaves are green above and whitish underneath, and hairless. This plant is a dominant species on the tundra in many areas. It commonly grows with sedges. It may form thickets with other species of willow along waterways and on floodplains. It grows in spruce woodlands and muskegs. It grows above the timberline in interior Alaska, and at the timberline in northern Alaska. It often sprouts and grows after wildfire, and it persists in open habitat. This species was formerly known as S. planifolia subsp. pulchra, a subspecies of S. planifolia, but has since been treated as a distinct species. The two willow species have overlapping distribution and similar appearance, but can be distinguished by the longer stipules in S. pulchra. In areas where both willows occur, S. pulchra is often found at high elevations. S. pulchra and S. planifolia also form natural hybrids. S. pulchra is one of the least bitter-tasting willows in Alaska, and in the springtime, young leaves may be harvested for human consumption. The leaves and shoots were eaten by the Eskimo raw and dried, or stored in seal oil for future use. The leaves were also used to brew tea and make soup. At Nunivak Island, parts of this plant were chewed to treat ailments such as mouth sores and pain. This willow also provides a good source of vitamin C. Apart from medicinal purposes, Native Americans used parts of willows, including this species, in basket weaving, to make bows and arrows, and for building animal traps.

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.
Shared flavor compounds
These compounds appear in both Tea leaf willow and Winged bean, giving them a molecular basis for flavor affinity, the pairing principle articulated by Francois Benzi and implemented in flavor-pairing research.
Why it works
The flavor-pairing hypothesis proposes that ingredients sharing significant aromatic compounds harmonize on the palate. Tea leaf willow and Winged bean overlap on 20 key compound(s), which is why classic culinary traditions, and our deterministic matching algorithm, place them together.
