Since posting the breaded cauliflower recipe, I had a friend ask “Can you reuse cooking oil?” The answer is YES, but it needs to be filtered first to remove the brown bits of food – if you reuse the oil without removing the browned bits, they’ll burn the next time you heat up the oil.
How to Filter Used Cooking Oil:
- Allow the oil to cool completely – I usually filter my oil the next day.
- Line a sieve with a piece of paper towel, a coffee filter, or a piece of folded cheesecloth, and place it over a bowl.
- Carefully pour the oil into the sieve. It may take a bit of time for the oil to filter through.
- Store the filtered oil in a closed container in a cool place.
Cooking oil can be used a couple of times if it’s been filtered after each use. When the filtered oil becomes dark, tastes funny, and begins to smoke when heated, it’s time to discard.
Cooking Oil Tip:
To discard cooking oil, fill an old container with the oil, and then place it in the freezer to solidify. When it’s garbage day, it goes out with the trash.
