Place the shredded cabbage and carrots in a large bowl and sprinkle a teaspoon of salt over them. Toss to combine. Let this sit for at least an hour to draw out excess water. Rinse and thoroughly drain (either use a salad spinner to spin dry it or lay it out on paper towels and blot dry.) Return the cabbage to the bowl.
Combine the dressing ingredients in a small bowl. Pour it over the cabbage mixture and stir until combined. Cover and refrigerate for at least 2 hours before serving.
