Copycat Outback Steakhouse Honey Mustard Dressing

Combine all ingredients in a bowl and mix well. Allow to set for at least 2 hours before serving, but overnight is best. You must use Grey Poupon Mustard--do not substitute. Steven Man suggests that you use 1 and 1/4 cups of light mayonnaise and a heaping 1/4 cup of Grey Poupon instead of the regular mayonnaise.
