(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.
Storing Used Oil. Used oil can be successfully stored in a cool, dark place for up to a month. Refrigeration or freezing increases the oilâs lifespan by several months. The oil may become cloudy during storage but this is not harmful and the oil will become clear upon reheating.
Another way to combine the herbs and oil is to heat the oil and herbs on a stove top. This will infuse the flavor of the herbs quickly and can prevent bacteria growth. Strain the herbs from the oil for a clear look. 5. Seal the bottle and store it in a cool, dry place for 1 week. The oil will quickly pick up the flavor of the herbs and will intensify over time. You should store your infused olive oil in the refrigerator and use it within a week if you're using fresh herbs or flavorings such as garlic, lemon or peppers.
