Stout is a dark, often bitter beer, originally produced by Guiness in Ireland, but now made by breweries all over the world. It adds distinctive character to this sauce. Serve with hot European sausages such as British Bangers or German-Style Beef Sausage.
1 cup grainy mustard
1/4 cup Dijon mustard
1/4 cup stout or dark ale
2 tablespoons firmly packed dark brown sugar
1/4 teaspoon freshly grated nutmeg
Salt and freshly ground black pepper to taste
Combine grainy mustard, Dijon mustard, beer, brown sugar, and nutmeg in a mixing bowl. Whisk well, and season to taste with salt and pepper. Refrigerate until ready to use.
Note: The sauce can be made up to 3 days in advance and refrigerated, tightly covered.
