(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.

Generally, sesame oil is one of the more temperamental oils. First off, keeping it in the fridge is a bad idea, when considering shelf life. Cold actually speeds up the rate at which the fats+lipids in the oil go bad. What you want to do is to keep it in a cool, dry place (a pantry would work great). As far as shelf life, you're looking at probably two to three months.
