Rinse the cabbage. Add water to the bowl and cover the cabbage completely. Drain into a colander and press down getting as much water out as possible. Pat dry on a towel. Finely shred the cabbage on a chopping board. Toss the cabbage and shredded carrots in a medium sized mixing bowl. Set aside.
In a small glass bowl add all the dressing ingredients. Whisk up until it is creamy.
Pour over cabbage, carrot and onion mixture and toss.
Chill this salad for at least 1 hour so the flavors will marry each other.
