(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).
Because of its delicacy, Iâve found that you can use more of this truffle oil than the standard import, and itâs too subtle for truffle fries. One of the best ways to experience true truffle oil is to make truffle butter. Into softened salted butter, blend in two teaspoons, or three for a more pronounced flavor. Wrapped tightly, you can store it in the refrigerator for up to two weeks. Eat it on artisan bread, mashed potatoes or corn on the cob.
