How to Make Fondue Mustard Sauce

In a medium saucepan, whisk together 1/2 cup Dijon mustard, 1/2 cup dry white wine (such as Sauvignon Blanc), 2 tablespoons granulated sugar, and 1/2 teaspoon salt.
Bring the mixture to a gentle boil over medium heat, whisking constantly to prevent burning.
In a small bowl, whisk together 2 tablespoons all-purpose flour and 2 tablespoons cold water until smooth. Gradually whisk the flour slurry into the simmering wine mixture.
Reduce the heat to low and simmer for 10-12 minutes, or until the sauce has thickened to your desired consistency, stirring frequently to prevent sticking.
Remove from heat and let cool slightly before serving. Enjoy warm or cold!
