How to Make It
In a skillet, toast the fennel seeds over moderate heat, stirring, for 2 minutes. Add the lemon juice and cook over moderate heat until reduced by half, 5 minutes. Whisk in the honey. Remove from the heat. Slowly whisk in the oil until combined. Stir in the shallots and rosemary and season with salt and pepper.
Using a sharp knife, remove the skin and white pith from the grapefruits. Working over a large bowl, cut in between the membranes to release the sections; discard the membranes. Add the sliced fennel, escarole, basil and 1 cup of the fennel dressing, season with salt and pepper and toss. Mound the salad on plates and top with the pomegranate seeds, goat cheese and walnuts. Serve the remaining dressing on the side.
