What is the secret to making good chocolates?

Hi, thanks for your answers. Could you explain please what conching is exactly?

@goldalex
I will discourage myself from answering such question as I will not do justice for you to find the answer yourself....and develop your initiative.

If you read it from the web on chocolate processing, or chocolate manufacturing books ,you can get a very detailed explanation including the history about CHOCOLATE CONCHING...It will explain.everything you want to know about it more than a brief answer from a poster here..
Got it.?

Can you explain the role of water?

As I know water is harmful for chocolate.

@DigambarGosavi water will cause the chicolate to thicken ..so its not required in chocolate

Water is harmful to chocolate. To qualify as chocolate, the product has to contain a minimum amount of chocolate liquor. https://food-technologist.biz/ - more information about industry standards.
