Quench your thirst with our Delicate Pineapple Punch, a citrusy drink that balances sweet and tart. (1 m L) salt 2 cloves garlic, finely chopped 4 strip loin steaks, 1 inch (2.5 cm) thick Olive Tapenade (recipe follows) To prepare marinade, combine first 7 ingredients (wine through garlic) in a heavy zip-lock plastic bag.
