We always make sambar with cluster beans/ kothavarangai. Make poriyal next to it and very rarely paruppu usili. Only cluster beans south Indian recipe, though I love to try a subji. My mom makes this kothavarangai sambar by sauteeing the vegetable first in oil and then boiling it, discarding the water (says its pitham) and proceed with sambar. It will be yummy, but MIL makes it as such boiling directly, I have no complains about that too. So I follow MIL’s method as Vj likes it that way. He is a big fan of cluster beans sambar, just contrast to my FIL, he hates it. This is a simple recipe, but when I made I thought I will click and post here in my blog for beginners.Serve with hot rice and poriyal/ kootu/ curry. We love it with a dollop of ghee.
