Long beans, are like any other beans except, its pod grow longer, about half a yard long and hence its also known as Yard long beans. They belong to the legume family (Cowpea / Blackeyedpea) and taste similar regular green beans but with less sweetness. Good when stir fried or steamed. Here's a simple stir fry version seasoned with Indian spices.
Normally a bunch might have about 50 to 60 beans, my recipe is for half of that. They can be refridgerated for 2 days but taste better when fresh and bright green.
