Beef Tenderloin with Port-Beach Plum Reduction
Buttery beef tenderloin serves as the dinner's grand centerpiece. A reduction sauce of port and a Nantucket favorite, beach plum jelly, enhances the meat. Tiny wild beach plums are too sour to eat out of hand, so they are often made into jelly, which balances their tartness. Red currant jelly is a readily available substitute.
