Agreed, without an ingredient list, is the fondue electric or liquid fuel, etc. there is no way to help - please provide more info!
I make fondue often - do you stir the cheese at the bottom when you pick it up on your fork? Figure 8's are best if you're using the proper bread that will hold up.
My recipe for fondue, basic, and I usually add a stronger cheese that makes it sharp
1 lb gruyere, shredded
1 lb Emmenthaler / Swiss, shredded
1/4 lb Appenzeller (I sometimes sub this for a different cheese as I find this one really strong)
1 1/2 tbsp cornstarch
1 large garlic clove
1 1/2 cups dry white wine
2 tsp fresh lemon juice
2 tbsp kirsch / when I don't have it on hand I just use any cherry liquor, just a dash
Dash of nutmeg
Dash of cayenne pepper
In a large bowl, toss the shredded cheeses with the cornstarch to coat.
Rub the inside of a large saucepan with the garlic, and discard. Pour the wine and lemon juice into the pan and cook over medium heat until hot but not boiling. Reduce heat to low and gradually stir in the cheese mixture, letting each addition melt before adding more. Stir in kirsch and cook for 2 min longer. Season with the nutmeg and cayenne. Do not stop stirring and use a nonstick pot.
Light the burner and transfer the mixture to the fondue pot. Regulate the burner so the cheese doesn't boil.. just keeps it heated. You will have to continue stirring it each time you dip, to keep the temperature throughout the dish.

Basically like Andy's lol. Sorry about that Andy, I had this page open a while!
