For an even richer flavor, consider using a high-quality, artisanal Brie. If the fondue becomes too thick, add a splash more milk to thin it out to your desired consistency. Feel free to experiment with different types of cheese! Gruyere, Fontina, or even a smoked Gouda would be delicious additions. For a festive touch, garnish the fondue with a sprinkle of chopped fresh herbs, such as thyme or parsley. To keep the fondue warm during serving, transfer it to a fondue pot or slow cooker set on low heat. Consider adding a pinch of red pepper flakes for a little heat.
