(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).
BeverlyAL. Since I use very little oil and they can turn rancid so fast, I store all of them except olive oil in the fridge once opened. Peanut oil turns rather solid but it's easy to set it out for a few minutes before using and it will be fine. I've never had my sesame oil turn funky on me.unny, I use olive oil up so fast I don't bother to store it in the fridge, but I do keep my sesame oil and canola oil in the fridge, because I rarely use them. Annie, get up off that lazy butt and get something useful done!
