Popular with American cuisine, deep frying food is the process of covering an item of food in some kind of batter before dipping it into a vat of boiling hot cooking oil. The end result often tends to be a warm, tender interior while the batter is turned into a crispy, golden brown crust. Once the cooking is done, the oil used for deep frying is often disposed of. If you are someone who doesn't want to toss away a batch of oil after only one use, you can store and save your deep fryer oil for future use.
Allow the deep fryer oil to cool before attepting to store it. Failure to do this can result in serious injury from burns.
Line the wire mesh strainer with either cheesecloth or multiple layers of coffee filters. This will catch any solid items that have been left in the grease, as well as filter out many harmful bacterias.
Place the funnel over the jar you will be storing your deep fryer oil in and put the cheesecloth-lined strainer on top of the funnel.
Pour the fryer oil into the strainer. Pour slowly so the oil can filter through the cheesecloth or coffee filters, and deposit into the jar. Stop pouring once the oil is within 1/4 inch from the top of the jar.
Remove the strainer and funnel and tightly screw on the cap.
Repeat steps 2 to 5 as necessary until the oil has been fully emptied from the fryer.
