The sautéing fennel, onion and saffron is my favourite of all kitchen aromas. They are also a classic combination that is used in various fish and seafood recipes. In fact, I love saffron so much we gave it to my daughter Lucy as her middle name. Mussels with saffron and fennel is an excellent appetizer. The complexities of the flavours cleanse the palate and ready you for the courses to come.
