Step 1

In a medium bowl, whisk together mayo, sugar, white wine vinegar, cider vinegar, yellow mustard, garlic powder, onion powder, and celery seed. Season to taste with salt and pepper (I like 1/4 teaspoon salt and 1/8 teaspoon pepper). Cover and chill until serving time, up to 4 days in advance.

Step 2

In a large bowl, add coleslaw mix. Drizzle with dressing to taste and toss to combine. This tastes best when eaten the day it is made.
