(AP) -- Phil DeVore pulls a folded piece of aluminum from a murky pond. The aluminum looks like a piece of siding that's blown off a building, but DeVore knows it's much more valuable than that. He slips a rubber band off the aluminum and unfolds it. He likes what he sees -- 50 or 60 glistening black leeches. They're your common ribbon leeches, Nephelopsis obscura to aquatic biologists.
After its initial use, cooking oil can be refrigerated or frozen and reused for another six hours of cooking (see References 2). Don't reuse cooking oil if it smells rancid or you can't heat it without smoke developing, as this indicates significant deterioration (see References 1 and 4).
If the oil is open, it is wise to store it in the refrigerator to keep it fresh for up to 3 years as well. However, an open container or jar of peanut oil stored in the pantry or on top of the counter will last for a shorter period â about 2 years. That depends on the quality of the peanut oil itself.
