7 of the World’s Oldest Food Finds

I have a 50-year-old box of vanilla extract that I keep around for the novelty and the vintage package design. I don't know what the bottle looks like because I've never opened the box. But that vanilla is downright fresh compared to some unearthed foodstuffs studied by archaeologists. Can you imagine a bowl of soup 2,400 years old?   

While excavating to make way for a new airport, Chinese workers struck liquid gold. Well, liquid gold if you happen to be an archeologist. Or really into soup. The soup, sealed so tightly in its bronze cooking pot that it was still in a liquid state, was discovered in a tomb near Xian. It didn’t look too savory, having turned green from 2400 years of bronze oxidation. It also still contained bones, which delighted archeologists, probably because they didn’t actually have to eat it.

That's one. There are six other examples of food surviving a very long time in a recognizable form (even if only after testing) at mental_floss. Link
