- transfer corn to a bowl. Take a deep pot and add water to it. Heat the pot over a high flame and bring the water to boil. Add salt and corns to it. Cook the corn kernels on medium heat for nearly 6-8 minutes. Once done, strain the excess water and transfer the corns into a glass bowl. While the corns are still hot, add chopped onions, tomatoes, chillies and fresh lime juice. Toss the ingredients well and check for salt before serving. Garnish the corn salad with freshly chopped coriander leaves and serve.
