This food from 3,000 years ago is still edible

Archaeologists opening ancient Egyptian tombs found pots of honey still liquid and edible after more than 3,000 years. Honey is one of the only foods that never spoils because bees engineer it to last. They fan nectar until its water content drops below 18 percent, so bacteria and mould cannot grow. They also add the enzyme glucose oxidase, which creates tiny amounts of hydrogen peroxide, a natural antiseptic. Combined with high acidity and low moisture, honey sealed away from water will essentially last forever. Crystallization does not mean it has gone bad.
