Combine all ingredients for the dressing with a whisk.
Toss part of it with the shredded carrots. You may not need all of the dressing. It will loosen up, so it's better to go slowly. You can always add, but you can't take it away.
I like to cover and refrigerate the slaw overnight so the flavors all come together and the sugar dissolves.
Reserve any remaining dressing in case you need it the next day.
