Yard Long Beans are the long, thin, dark green beans that you find in many korean supermarkets here in the US and these are quite popular in India too. I meant to take a picture before I started to chop them up but forgot so here's a picture from Wikipedia.
I had a thoran made with these at Shobana periamma's place and loved it. My mother-in-law also makes a lip-smacking thoran with this. During my initial attempts at making this I couldn't get it to cook properly but now it works out fine when I follow this method:
YARDLONG BEANS THORAN
Yardlong beans - 1 bunch, ends trimmed, chopped fine
Onion - 1/2, chopped fine
Oil - 1 tsp
Mustard - 1/2 tsp
Urad dhal - 1/2 tsp
Curry Leaves - few
Coconut - 2 to 3 tbsp, shredded
Cumin seeds - 1 tsp
Green Chillies - 6
Garlic - 1 small to medium clove
1. Heat oil in a wide, shallow pan, add mustard seeds and urad dhal, once they crackle add the curry leaves. Now add the chopped onions and saute till light brown.
2. Next add the chopped beans and some salt. Saute this for about 5 minutes after which 1/3rd cup of water should be added. Cover the pan and keep on a med. to med - high flame. Check the pan often since the water will evaporate super-fast. Toss and repeat this until the beans are almost done.
3. Add the ground coconut paste at this point and let this cook until completely done and the thoran is now ready.
