This was the other part of my hand made Christmas presents this year..
Quite easy if you follow these few steps as below:
Use kettle and place smaller one on top of it so boiling water in larger one heat smaller one. It is most common mistake to put chocolate straight on to the heat. Metal bowl also can be used instead of smaller kettle.
Use chocolate chips or just a normal dark or milk chocolate, stir until chocolate is melted. (Use as many chocolate as you would like to use, it's never too much) :)
Then pour in tray (with lined baking paper) or in special silicone forms. Let it cool, and then place in refrigerator. Wrap in baking paper or up to imagination.
*vanilla extract, cardamom, cinnamon or different nuts and dried fruits can be added as well.
