Depending on your fondue pot, you'll need to keep the pot at a low even temperature (around 120 degrees) so you don't burn the cheese. Add chicken broth and cornstarch to your fondue pot first, and quickly mix them together using a fork or whisk so the cornstarch does not clump up. Then add the rest of your ingredients and stir until the cheese is fully melted and smooth for dipping. You can transfer to another bowl, but use it immediately so that the cheese stays melted.

Double boiler method: Just heat the double boiler so that the water from the first pot is steaming the second pot and then follow the recipe per the directions. Transfer the cheese to a separate dish for serving and serve immediately.
