Drinking chocolate?
Drinking chocolate is similar to hot chocolate, but is made from melted chocolate shavings or paste rather than a powdered mix that's soluble in water.[1]

"Drinking Chocolates" are made from real chocolate as opposed to "Hot Cocoa" which is made from cocoa powder (the powdery remains of chocolate liquor after cocoa butter is removed). When you purchase a package of drinking chocolate it will often be in the form of chocolate shavings or chunks.
