Notes
If there are still lumps of chocolate that remain after cooking, just stir until they melt.
The chocolate mixture will be extremely hot so be careful when eating. It's a good idea to let it cool a bit so that it's thicker and easier to dip into.
If the fondue is too thick, you can just add in some more heavy cream or a little bit of milk and stir
If there are still lumps in your fondue, just stir it a bit more.
