Can you only heat fondues with tea lights or is there another way?

There is nothing more fun than inviting a bunch of friends over, creating a wonderful chocolate fondue with a great selection of fruits and goodies to dip into it and then just enjoying yourself along with a nice glass of wine.

So here is a basic recipe for a good chocolate fondue;

12 ounces of dark chocolate (I prefer to use really good quality chocolate)
8 ounces of heavy cream
Pinch of salt (do not leave this out)
Things for dipping such as fruit, dried fruit, biscotti, bread, marshmallows.

Method:
Warm the cream gently over a medium heat. Do not boil the cream, just wait till you see tiny bubbles.
Add the chocolate and whisk until it is all mixed in.
Put the mixture into a fondue pot and heat it on a low flame.
Put the dippables onto a big plate with fondue forks etc and enjoy.

For a slight twist, add some alcohol such as Baileys irish cream to the chocolate mixture.
