Can you use an old piece of aluminum foil as a cutting board cover?

Yes, an old piece of aluminum foil can be used as a cutting board cover. It serves as a disposable barrier between the cutting board and the knife, protecting the board's surface from cuts and scratches. After use, the foil can be easily discarded, keeping the cutting board clean. However, it's not a long-term solution as foil can wear out quickly and isn't as durable as a proper cutting board cover.
