How to Make It
In a medium saucepan, bring 1 inch of water to a boil. In a medium stainless steel bowl, combine the Fontina cheese with the butter, eggs, egg yolks, milk and Gorgonzola cheese. Set the bowl over the saucepan and cook the mixture over low heat, stirring the cheese constantly with a wooden spoon, until it is melted and smooth, about 10 minutes. Pour the fonduta into shallow bowls and serve at once with toasted baguette slices.
