As an appetizer or main dish, this cheese fondue is a fun and interactive meal your little ones can help with. For both little and big kids: Let them help shred the cheese and stir it into the simmering apple juice, and choose and help prep all the dippers.
Suggested Dippers (choose 3 to 4)
Cook’s Note: Never leave a child unattended in the kitchen. Limit the child to tasks that are safe and age-appropriate.
Bring the apple juice to a simmer in a medium saucepan over medium heat. Toss the Gruyere and cornstarch in a medium bowl. Add to the simmering juice by the scant handful, whisking constantly until smooth and letting the sauce come to a boil between additions, about 30 seconds. Remove the saucepan from the heat, stir in the Parmesan and mustard and season with ½ teaspoon salt and a few grinds of pepper.
Pour into a serving bowl, and serve with the dippers of your choice.
