Filter Fry Oil for Reuse

Do you like to fry food but don't because the cost of fresh cooking oil is too high? One of the best things about frying is that the oil can be used more than once and used oil can add flavor. Don't worry about the cost of expensive "professional" or "industrial" oil filters. Here is how to do it on the cheap.

Steps

  1. When you are done frying for the day, scoop out any large chunks that are left in the oil.
  2. Allow the oil to cool to 150 - 170 °F, 65 - 75 °C.
  3. Place a coffee filter or a cheesecloth in the mason jar and roll the edge of the filter over the lip of the jar.
  4. Loosely install just the ring and make snug to secure the paper coffee filter or cheesecloth.
  5. Pour the warm oil into the filter through the hole in the ring being careful not to overfill the filter. It will take a few minutes for the oil to pass through. Caution, the oil is still hot enough to cause a burn.
  6. When the oil has run through the filter, carefully remove the ring and filter. Discard the filter, place the lid on the jar and secure with the ring.
  7. Store your oil for your next cooking adventure, be it deep frying, stir frying, pan seasoning or just lubricant duty.
  8. Finished.

Tips

  • You can filter the oil at room temperature but the oil will flow better when it is warm.
  • Dark oil, after filtering, is a sign the oil maybe breaking down and is not in pristine condition. However dark does not mean bad oil.
  • Ideally, select a mason jar or jars that will hold all the oil and keep the bottom of the filter out of the clean oil.
  • Always try to fill the jar leaving no air head space. The oxygen in the air will even in storage react with the oil and start breaking it down.
  • How long you can store the oil depends on many factors including; fry temperature and how long it has been used. First use fry oil can last well over a week if the temperature is kept to 375 °F / 190 °C and was used only a short time, as when frying a small fish.

Warnings

  • Be very careful handling hot oil. Even 150 °F / 65 °C oil can cause a burn in seconds.
