1/2 cup olive oil
2 teaspoons grated lemon zest
1/4 cup plus 1 tablespoon freshly squeezed lemon juice (3 lemons)
2 tablespoons minced shallots
1 teaspoon celery seed
1/2 teaspoon celery salt
1/2 teaspoon anchovy paste
Kosher salt and freshly ground black pepper
5 cups thinly sliced celery hearts, tender leaves included, sliced on an angle (about 12 stalks)
4-ounce chunk Parmesan cheese
2/3 cup toasted walnuts, coarsely chopped
Whole flat-leaf parsley leaves
1. At least 1 hour before you plan to serve the salad, whisk together the olive oil, lemon zest, 1/4 cup of lemon juice, the shallots, celery seed, celery salt, anchovy paste, 2 teaspoons salt, and 1 teaspoon pepper.
2. Place the celery in a mixing bowl and toss it with the remaining 1 tablespoon of lemon juice and 1/2 teaspoon of salt. (Even though these ingredients are in the dressing, believe me-this step makes a difference.) Add enough dressing to moisten well. Cover and refrigerate for at least an hour to allow the celery to crisp and the flavors to develop.
3. When ready to serve, arrange the celery on a platter, shave the Parmesan over top of the celery, and sprinkle with walnuts, parsley leaves, salt, pepper and serve immediately.
