The recipe, as written, is absolutely lovely. I opted to swap out the extra virgin olive oil for a toasty walnut oil that I think works really well with the brightness of the orange juice in the dressing. If you don’t have walnut oil on hand, olive oil will work just fine. And a note on fennel: when the recipe discusses the fronds, those are the delicate, almost frilly leaves connected to the stalks. As the directions indicate, you’ll reserve them to lay atop the salad.

Wash the watercress and cut off the stems. Place leaves in your favorite salad bowl.
Cut the fronds off the fennel stalks and reserve. Discard the stalks. Mince the fronds and set aside. Cut a slice off of the bottom of the bulb, then cut it lengthwise in half. Slice the halves crosswise into thin slices and lay in with the watercress.
Remove the orange peel by slicing off the top and bottom of the orange. Cut around the orange with a serrated knife, using a sawing motion to cut off the white pith as well as the peel. Slice the oranges into thin rounds and add to the salad.
Juice one orange for the dressing. Mix the walnut oil and 1/3 cup fresh orange juice together and season with salt and pepper. Mix with the salt, and sprinkle with the minced fennel leaves and toasted walnuts.
