When Howard Carter and Lord Carnarvon opened up King Tutankhamun’s tomb in 1922, they found a fascinating stash of highly-treasured items: jewellery, weaponry, gold, furniture, statues and… honey.
Remarkably, after sitting in the tomb for 3,000 years, scientists determined that the honey was almost certainly still edible (although I doubt anyone put their ‘mhoney’ where their mouth was). That’s a long shelf-life.
