Fennel Marinated Roast Pork

The hint of anise in wild fennel, usually reserved for fish preparations, is a perfect foil to the dullness of fresh pork, bringing a vibrant delicacy to its flavor. Wild fennel is much more richly perfumed than the bulb fennel found in the market, but if the former is unavailable, the feathery leaves of bulb fennel may be substituted—the pastis will reinforce their somewhat attenuated accent. The subtlety of mingled flavors is more pronounced when the pork is eaten cold the following day.<
