Used Cooking Oil, usually shortened as UCOs, are oils and fats that have been used for cooking or frying. UCOs are usually found in the food processing industry such as restaurants and fast foods, as well as in households.
If you fry food on a regular basis, you can save the UCOs to be used in frying by straining it with a coffee filter or several layers of cheesecloths to remove any particles and crumbs.
However, keep in mind that you should only reuse UCOs once or twice at maximum.
