Makes 4 Servings
1 cup hazelnuts
1 1/2 tablespoons red wine vinegar
1/2 teaspoon kosher salt
Freshly ground black pepper, to taste
1/3 cup extra-virgin olive oil
8 large celery stalks with leaves, thinly sliced
2 ounces good parmesan cheese, shaved
1. Preheat the oven to 350° F. Spread hazelnuts in a single layer on a rimmed baking sheet. Toast, tossing once halfway through, until nuts are golden, 7 to 10 minutes. Pour the nuts into a clean dish towel and use the towel to rub off some of the skins (do not try to be thorough here, it takes too much time, just get rid of what flakes off easily). Cool and coarsely chop the nuts.
2. In a small bowl, whisk together the vinegar, salt, and pepper; whisk in the oil. Combine nuts, celery and leaves, and cheese in a large salad bowl. Add vinaigrette and toss gently to combine.
