 - 1 tablespoon all-purpose flour
 - 1 teaspoon butter
 - 2 eggs, beaten
 - 3/4 cup white sugar
 - 1/4 cup water
 - 1/4 cup white wine vinegar
 - 1/4 cup creamy salad dressing (e.g. Miracle Whip)
 
- In a saucepan, combine the dry mustard, flour, butter, eggs, sugar, water and vinegar. Cook over medium-high heat until thick and nice and smooth, stirring often. If necessary, add up to 1 tablespoon additional flour. Set aside to cool.
