8 oz. (approximately) Miracle Whip
1/4 cup cider vinegar
1/4 cup rice vinegar
1 tsp. yellow mustard
1-2 tsp. brown sugar
1-2 tsp. celery seed
1-2 tbsp. sweet pickle relish or a couple of sweet gherkins or some bread and butter pickles, chopped fine.
Whisk all together, and taste.
Personally, I like it a little more relaxed so I put the dressing on a couple of hours before I serve it.
