Place a small frypan on medium heat and add the cumin seeds. Toast them until they become aromatic then remove them from the heat. When cool enough to handle grind to a fine powder. Set aside.
Place the corn, jaggery, and one cup of water in a small pot over medium heat and cook until corn is tender. Drain and set aside to cool.
Place drained corn in a bowl, and add the cucumber, onion, tomato, capsicum, carrot, chilli, and pomegranate seeds. Mix well, cover, and refrigerate for one hour.
to serve
Sprinkle the ground cumin, chaat masala, chilli powder, and salt over the vegetables, and toss to coat.
Transfer to a serving plate, pour the lime juice over, sprinkle with the coriander leaves and sev, and serve.
notes
Note that the times above allow for the cooked corn to cool. This may vary with your taste - a warm salad is quite good to serve during the cooler months.sev are short fried chickpea flour noodles and are readily available from good Indian grocers.
