Long beans are an asian veggie often compared to okra. Raw, they looked like medussa's ponytail. A bit rough, a bit tough, a bit, well, snakey.
We made them into a stir fry with water chestnuts, baby corn, bamboo shoots and dried chilis in oyster sauce. Long beans have a nutty flavor and are quite tough when not cooked enough. This isn't the sort of thing to blanche; I liked them best when they were really, really cooked. I steamed them in the pan as well as stir frying them.
Eating them was another story... You can see how long the bean stretches from chopstick to plate!
