Here are a few tips, courtesy of Nando's: buy the best quality oil you can afford; soak raw chips in water and then dry them before frying in order to remove excessive moisture – this will delay the oxidation of oil, a process that can result in dangerous breakdown products; filter oil after use to remove small pieces of food; store oil in a closed container in a cool, dry place; and throw away oil if it is dark brown, tastes and smells unpleasant or is stringy.
