Whisk together the honey, vinegar, mayonnaise and mustard in a small bowl. Slowly drizzle in the oil, whisking to combine. Season well with salt and pepper. (Alternatively, add the honey, vinegar, mayonnaise and mustard to a mason jar with a lid, cover and shake well. Add the oil and shake well once more.)
Combine the cabbage, red onion, Chinese celery and pickles to taste in a large bowl. Pour the dressing over the vegetables and mix well. Taste and season with salt and pepper. For an extra kick of flavor, mix in some pickle juice if using to taste. Refrigerate until ready to serve.
