This recipe is easily halved or doubled, depending on how many you're serving and how much sauce they like. If you don't keep honey mustard in your kitchen, you may swap in 2 tablespoons of honey and 2 teaspoons of prepared yellow mustard for the honey mustard. Store sauce in the fridge for up to one week.
