Hyacinth Beans (Fresh, Immature)

Fresh Hyacinth Beans (Immature Seeds): Nutrition and Guide

Fresh, immature hyacinth bean seeds — harvested from the pod before they dry — are treated as a vegetable across South Asia and parts of East Africa, eaten in their tender state before the anti-nutritional factors of the mature seed develop significantly. At this young stage they are sweet and tender with a mild, slightly nutty flavour. In South Indian cooking, fresh avarekai seeds are used in usli (a spiced stir-fry), in sambar, and in simple spiced preparations with mustard seeds and coconut. The fresh immature seeds are safe to eat after brief cooking without the extended soaking required for the mature dried bean, though a light boil before stir-frying is generally recommended.

Nutritional Value and Uses

Fresh hyacinth beans (immature seeds) provide 46 kcal and 2.1 g of protein per 100 g — much lower in calories than the dried mature seed because of high water content. They provide some fibre, vitamin C, iron, and B vitamins. Cook by blanching briefly, then stir-fry with mustard seeds, curry leaves, turmeric, and grated coconut for a South Indian-style preparation, or add to vegetable curries and soups. Availability in the UK is limited to South Asian grocery stores during the brief season when fresh hyacinth beans are imported.
