Ingredients
1 medium celery root (about 12 ounces)
1 Granny Smith apple
Juice of 1 lemon
1/2 cup nonfat plain yogurt
2 tablespoons heavy cream
4 teaspoons Dijon mustard
1 tablespoon coarse salt
1/4 teaspoon freshly ground pepper
Preparation
Peel celery root; core apple. Grate both on the large holes of a box grater. Place in a medium bowl, and toss with lemon juice to prevent discoloration.
In another bowl, whisk together yogurt, cream, mustard, salt, and pepper. Add to grated celery root and apple, and toss to combine. Refrigerate until ready to serve.
