Chef John's Waldorf Salad

Whisk mayonnaise, creme fraiche, lemon juice, tarragon, sugar, salt, black pepper, and cayenne together in a bowl.

Step 2

Place apples, celery root, grapes, and walnut pieces in a large bowl. Toss with about 1/2 cup of dressing. Add more dressing until salad components are well coated but not swimming in dressing. You might not need all the dressing.
