- Combine the cabbage/carrot mixture with the grated onion in a very large bowl or heavy-duty plastic bag. Whisk together the remaining ingredients to make a smooth dressing. Refrigerate for at least two hours or overnight.
- About 1 hour before serving, remove the cabbage mixture from the refrigerator and give it a good tossing with a fork.
- Pour the dressing over the cabbage mixture and toss well to coat.
- Cover and refrigerate until ready to serve.
Note: It's important that the onion be grated and not merely chopped. You'll have to drag out your old grater, but don't skin your knuckles.
