This is from Delia Smith’s ” Summer Collection”.
First pre-heat the grill to its highest setting, then rub the corn kernels with a trace of olive oil.
Place them under the grill and toast them for roughly 8 minutes, turning them from time to time so that they toast evenly. When they're cool enough to handle, hold each one firmly with a cloth and scrape off all the kernels using your sharpest knife.
Mix these together with all the other ingredients, taste to check the seasoning and serve .
