In a large salad bowl, whisk together the sour cream, mayonnaise, mustard, cider vinegar, salt, and pepper to create the dressing. Add honey if you prefer a touch of sweetness.
To the bowl with the dressing, add the cooked macaroni, drained onions, bell pepper, celery, radish, and pickles if using. Stir until everything is well coated with the dressing.
