(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.
As with hemp oil, delicate nut oils like hazelnut should be stored in the refrigerator once opened to preserve freshness. Buy only the amount youâll use within three to six months for peak flavor. Best uses: Skip the frying pan and use hazelnut oil to gussy-up cooked rice, quinoa, or oatmeal.
