Every summer picnic needs a creamy coleslaw to accompany all your picnic foods. This tangy version with the addition of jicama makes the perfect summer side dish.
In a large bowl, combine the cabbages, jicama, carrots and scallions.
In a small bowl, blend the buttermilk, mayonnaise, lemon juice and celery seeds. Toss the buttermilk dressing with the cabbage and mix well. Season with salt and pepper and more lemon juice to taste.
