Cheese fondue consists of a blend of cheeses, wine and seasoning. To prepare the caquelon it is first rubbed with a cut garlic clove. White wine is slightly heated with cornstarch, and then grated cheese is added and stirred until melted. It is often topped off with a bit of kirsch. The cornstarch or other starch is added to prevent separation. The mixture is stirred continuously as it heats in the caquelon.
When it is ready, diners dip cubes of bread speared on a fondue fork into the mixture.
