This has got to be one of the very best coleslaw recipes I have ever found.  It was originally posted here:

Traditional Creamy Coleslaw

• 1 cup mayonnaise
• 1/4 cup sugar
• 2 Tbs rice vinegar
• 1-1/2 Tbs lemon juice
• 1 Tbs prepared horseradish
• 1/2 Tsp onion powder
• 1/2 Tsp dry mustard
• 1/2 Tsp celery salt (I use celery powder personally)
• 1/2 Tsp salt
• 1/2 Tsp ground black pepper
• 1 (28 oz) package of coleslaw mix - or, you know, you can shred a head of cabbage and grate some carrots.

Whisk up all of the non-vegetable ingredients in a large bowl until the sugar is dissolved.  Fold in the coleslaw mix.  Cover bowl and refrigerate 1 hour before serving.
