When I was a kid, my Uncle was a blacksmith at the Qunaba Sugar Mill near Bundaberg. I recall the name Red Sugar being the term used by the Chinese workers for Brown Sugar. Something about hot food / cold food and colours being assigned to different foods. RED didn't refer to actual colour, but rather the type of sugar it represented in their cuisine.

Another wonderful episode -a pleasant surprise to find it was about chocolate and not the terrible 1976 movie adaptation of H.G Wells novel 'The food of the gods and how it came to earth'.

At 5min 17sec TVs Doctor Joel Gilmore says 'Chemistry which is really applied Physics' - this is clearly a mistake.

Greg, Please don't keep saying mouthfeel (shudder)

Given the methylxanthines in chocolate such as theobromide (Chemistry, not applied physics ) bind to receptors in canines in a way which results in being slower at clearing from body than in humans this leads to a much lower LD50 for dogs, Does this mean (diverging into the cryptoZoo) that chocolate could be used to indicate if someone is a werewolf?

The chemistry of making chocolate is complex and fascinating with six different crystalline structures each leading to a different 'mouthfeel' and why if you melt chocolate and allow it to set it may not taste as good.

mmmmm Moooooooouth Feeeeeeeeel

I like your werewolf idea. I feel like this is a missing Buffy episode.
