Honey Mustard Salad Dressing

I got this recipe from a friend at work. It is a really good dipping sauce... And it's great on a spinach salad with either boiled eggs, cherry tomatoes, and extra bacon or smoked chicken or turkey and fruit-nut trail mix.

4 tablespoon mayonnaise
1 tablespoon mustard, yellow or Creole or whatever
1/8 to 1/4 teaspoon cayenne pepper
1 tablespoon honey
1 tablespoon granulated sugar
1 tablespoon bacon drippings or oil (we use olive or canola)
Apple cider vinegar
Real bacon bits (optional)

Combine first 6 ingredients until smooth. Add enough cider vinegar to thin to the proper consistency. Stir in bacon bits as desired. Chill for at least 1 hour before serving.
