Make sure each addition of cheese is melted before adding the next batch.
If fondue becomes too thick, stir in 1/4 to 1/2 cup heated wine.
Cut bread so that each piece has a part of the crust. Spearing the bread through the crust will prevent it from sliding off the fondue fork when dipping.
Try not to drop your cube of bread into the cheese. If that happens, you owe the host a bottle of wine!
