Non sticky chocolate?
 

I like the crunchy and snappy feel of cold dark chocolate.
I don't like the sticky texture after they melted in the mouth. However, I
don't mind hot chocolate drink.
Is there chocolate that doesn't melt into sticky liquid? Either don't melt,
or melt into watery liquid?

Ehhh dark chocoate is ok. Milk chocolate + caramel = mans greatest invention!
