The scorn heaped on Hershey's chocolate always amuses me. The type and percentage of chocolate is varied to suit the taste of the customer. English candy bars taste just as peculiar to most Americans as ours do to them. Cadbury's always taste mealy. Hersheys, like most chocolate companies, produces several kinds of bulk chocolate for use by other confectioners.
Some prefer Belgian, Swiss, etc., but all the large companies use bulk chocolate of several types, according to the product desired.
For the best sipping chocolate, try Ybarra's, from Mexico. The best in the world!
