Special Mustard

I cloned this recipe many years ago, after tasting it at a catered yacht party. The hostess wouldn't give out the recipe, but her helper told me it has horseradish and brown sugar in there. Bingo! I captured it perfectly. It is delicious as a sandwich spread, especially on a ham sandwich.

1  jar (4 oz)  Dijon mustard
1  cup  apple cider vinegar
3  eggs
1  cup  light brown sugar
2 - 3  Tbs  horseradish
1  Tbs  cornstarch

Combine mustard and vinegar and let stand at room temperature overnight.

The next day, beat eggs and brown sugar together. Dissolve cornstarch in a small amount of cold water. Add this to the egg mixture, along with the horseradish. In a double boiler, over boiling water, cook and stir constantly until thickened.

Cool and store in the refrigerator.
