My mother, who believes in never, ever throwing food away until you can actually see the mold growing, bought a giant plastic jug of honey that she used for most of my childhood. It got sludgier and sludgier as the sugars solidified. Eventually, you could only get it liquid enough to use if you put it in the microwave for a while. And then, even that didn't work and it was basically just a solid mass of amber sugar gunk.

So I always found that story hard to buy and now I know it wasn't true. Thanks.
