Why is kirsch used in cheese fondue?

* Flavor: Kirsch is a cherry brandy that adds a complex, fruity, and slightly bitter flavor profile to the fondue. It complements the rich and savory flavors of the cheese, creating a well-balanced taste.

* Melting properties: Kirsch helps the cheese melt smoother and more evenly. It also helps to prevent the cheese from becoming too thick and sticky, making it easier to dip into.

* Livening up the fondue: Kirsch adds a touch of alcohol to the fondue, which helps to bring out the flavors of the cheese and other ingredients.

* Tradition: Kirsch is a traditional ingredient in Swiss cheese fondue. It's a classic pairing that has been enjoyed for centuries.

While Kirsch is a common addition to fondue, it's not always necessary. There are plenty of cheese fondue recipes that don't include Kirsch, and you can certainly choose to omit it if you prefer.

Ultimately, whether or not you use Kirsch in your cheese fondue is a matter of personal preference. If you enjoy the flavor and appreciate the traditional touch, then it's a great addition. However, if you're not a fan of cherry brandy or prefer a less boozy fondue, then you can easily leave it out.
