This is half way between a dahl and a curry, where a few tins of regular sweetcorn are transformed into something fragrant and special by the help of the spices from the back of your cupboard. I¡¯ve suggested using a stick blender to give your corn a nice creamy texture, but if you don¡¯t have one, don¡¯t worry, just mash some of the corn by hand using a potato masher instead.
