Salmon with Orange-Fennel Sauce
The mild acidity of fresh orange juice cuts the richness of salmon. Be careful not to marinate longer than 20 minutes; as in ceviche, the citrus marinade can "cook" the fish. Crush the fennel seeds with a mortar and pestle, or place them in a zip-top plastic bag on a cutting board and crush with a heavy pan. You can prepare the marinade up to one day in advance and refrigerate in an airtight container until ready to use.
