The Answer
The question in this edition is:
What substance do many people crave, but its separate components stink?
The answer: Chocolate
Acetic acid by itself smells like vinegar. Dimethyl trisulfide smells like cabbage, and 3-methylbutanic acid has a rancid smell. These are just three of the 25 substances that produce chocolate’s attractive aroma. It is the just right combination of the many compounds that makes chocolate irresistible – not to mention all the other wonderful substances we add to it, such as milk, sugar, almonds, salt . . . . Read more about the research that narrowed down the key 25 substances that make so many people crave chocolate.
