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.
Remember to change your cooking oil regularly for health reasons. Why? Because the chemical composition of UCO contains carcinogenic substances (promotes carcinogenesis, the formation of cancer) that resulted from the frying process.
Furthermore, each time you reuse the oil, its quality deteriorates and the smoke point (the temperature at which it will burn) decreases.
