Add groundnut oil in a wok(kadhai) and heat it on high for frying. In the meanwhile , add the chopped cilantro, green chillies, salt and turmeric in the batter. Also add roasted cumin powder, chaat masala (for added 😉 chatkare) and hing and mix them well. [ P.S. : Recently I am introduced to the benefits of deep frying in unrefined ,non-compressed , pure extracted oils like groundnut oil ,coconut oil. Hence I have replaced my refined oils with Olive oil for dressing and sauteing, groundnut oil for deep frying and Desi ghee for applying and making sweets. You may follow your family tradition and use mustard oil /coconut oil/ sesame oil for frying too. ]
