Hot Mustard and Olive Sauce for Fondue

< Return to recipes

This is such a hot and tangy sauce that it will add zip to any fondue you serve, but remember that it has a mayonnaise base and might be just dandy with cold cuts, with salad greens on the side.

    1/2 cup dry mustard
    1/2 cup vinegar
    12 seedless green olives, chopped
    1 tbsp. butter
    1 egg, beaten
    1/4 cup sugar
    3/4 cup mayonnaise


    Combine the mustard, vinegar, and olives in a bowl. Cover and let stand overnight in the refrigerator.
    Next day, allow this mixture to come to room temperature. Place butter in the top of a double boiler and allow it to melt. In a bowl, mix egg, sugar, and salt, beating well with a wire whisk. Add this mixture gradually to the warm butter and beat constantly. Gradually add the mustard and vinegar mixture and stir constantly.
    When the mixture actually coats a mixing spoon, remove from heat and allow to cool. About 20 minutes before serving, whip in the mayonnaise.
