Step 1: Botanical Identification:
Cluster bean (Cyamopsis tetragonoloba) is an annual legume plant. It is an important source of guar gum (used as a thickening agent in food industries) and is widely consumed as a fresh vegetable in Indian households.
Step 2: Evaluating Local Names of Vegetables:
Let us identify each of the vernacular names listed in the options:
• Sem ki Phalli: This refers to hyacinth beans or broad beans (Lablab purpureus), which are wider and flatter than cluster beans.
• Ker: These are tiny, sour, wild berries harvested from the thorny bush Capparis decidua, typical of the desert regions of Rajasthan.
• Sangri: These are the slender, long green pods harvested from the Prosopis cineraria (Khejri tree), commonly used in the Rajasthani delicacy Ker Sangri.
• Gawar ki Phalli: This is the widely used Hindi term for cluster beans. They grow clustered together in vertical groups, hence their English name.
Step 3: Verification:
Therefore, cluster beans are universally known in Indian culinary markets as Gawar ki phalli.
