German-Style Slaw

I love this slaw. It's easy to make, tastes great and only gets better the next day!

German-Style Slaw

2 packages of shredded cabbage (16 oz packages)
1 medium onion, finely chopped
3/4 cup sugar
3/4 cup cider vinegar
1 and 1/2 teaspoons celery seed
1 and 1/2 teaspoons salt
1/4 teaspoon coarse-ground black pepper
3/4 cup canola oil

Place cabbage into a large plastic or glass bowl. In a small saucepan, combine sugar, vinegar, celery seed, salt and pepper. Bring mixture to a boil. Add oil. Return to a boil and cook over medium heat, stirring constantly, until sugar is dissolved. Pour dressing over cabbage; toss to coat well. Cover and refrigerate at least 3 hours or overnight before serving.
