Lots of things affect the life of the oil too. What you fry in it has a tremendous influence: meat juices and vegetable juices get into the oil and break it down, salt will break it down very fast too, never salt over or around the fryer. Crumbs will burn in the oil and affect it too if you don't strain it religiously. Light, particularily sunlight, will break down the oil prematurely too, so keep the oil covered and out of direct light. |
