ave you ever bought a chocolate bar or a chocolate bonbon, and when you impatiently opened the sweet package, you discovered an unappealing layer of something white on the surface of your supposed-to-be-pleasurable snack? And if you took a bite of that chocolate, it crumbled in your mouth in a kind of sandy way? Well, don’t worry, that chocolate bar wasn’t old or spoiled, and the white thing is not fungus, no – the problem is in a process called the ‘tempering’.
