The Licking Phase of Chocolate Melting

As soon as the chocolate hit the slimy wet tongue, the outer layer immediately began to change from a solid to a liquid. This first step is what researchers call the licking phase. And in this stage, the tongue is warmer than the solid chocolate, so the chocolate begins to melt. As soon as the tongue experiences this smooth sensation, saliva enters the party? Yep. You are. I thought you'd never ask.
