Why Chocolate Melts in Your Mouth, Not Your Hand

Why does chocolate melt in your mouth but NOT in your hand? The answer is cocoa butter — the fat in chocolate melts between 93 and 100°F, perfectly balanced between your palm's temperature and your mouth's. We break down the science: cocoa butter's razor-sharp melting point, the six crystal forms of chocolate, why proper tempering gives you that perfect snap (Form V crystals), and why your tongue beats your palm every time. TRY IT YOURSELF: the snap test, the palm test, and the mouth test — all you need is a chocolate bar.
