The partner to kali on Arudra Darshan morning is a kootu of seven (ezhu) vegetables, an old Tamil Brahmin custom that uses whatever native winter produce is at the market: pumpkin, ash gourd, raw plantain, sweet potato, broad beans, colocasia and chow-chow are a typical set, and no onion, garlic, tomato or 'English' vegetables go in. They simmer in tamarind water with soft toor dal and a paste of roasted coriander, chana dal, red chillies and coconut, giving a thick, tangy, gently hot stew that cuts the sweetness of the kali. Common mistake: adding tamarind before the vegetables are cooked, which keeps them hard; cook them first in plain water until a knife goes in easily, then add the tamarind and boil until its raw smell has gone. Chef's tip: roast the paste spices until the chana dal turns golden-red, which gives the kootu its depth.
