How do you "purify" frying oil for re-use? I have a deep fryer and have only used it for chicken, but this weekend I want to fry shrimp and chicken. Oil is way too expensive to throw out. What's the best and easiest method? I plan to use vegetable oil, if that makes a difference,

You can strain oil through a coffee filter but not sure you can make it like new. Once oil is heated to temperature, it will start to break down over time.

I have poured peanut oil through a coffee filter and re-used it, but with each re-use the smoke point of the oil goes down somewhat. You should be fine as long as you don't overheat the oil.

I have a turkey fryer and hate to throw away oil myself, however impurities like fats do collect in the oil and decrease the smoking point as CookieWeasel said. Also, the oil's flavor will change with each new food that you cook in it so I would suggest frying your shrimp last.

A lot of times if its NOT too bad (dark in color) you can pour it through a coffee filter. If it has an odor or funny taste then preheat your deep fryer and put in a peeled raw potato cut into thirds-it will absorb any bad odors and flavors. It takes about five mins just until the potato is brown. This should help a lot. I hope it helps. Brian
