- 2 tablespoons lemon juice
- 3/4 teaspoon grated orange zest
- 1 1/2 tablespoons fresh orange juice
- 3/4 teaspoon salt
- 1/4 teaspoon fresh-ground black pepper
- 6 tablespoons olive oil
- 1 3/4 pounds fennel bulbs, cored and shaved as thin as possible
- 1 small red onion, chopped fine
- 1/2 cup grated Parmesan, or a chunk of Parmesan for making curls
- In a large glass or stainless-steel bowl, whisk together the lemon juice, orange zest, orange juice, salt, and 1/8 teaspoon of the pepper. Add the oil slowly, whisking. Add the fennel and onion and toss. Let stand at least 5 minutes but no more than 1 hour.
- To serve, top the salad with the grated Parmesan, or with a few curls of Parmesan shaved from the chunk of cheese using a vegetable peeler. Sprinkle with the remaining 1/8 teaspoon pepper.
