Have your butcher cut ribs down length of slab into two pieces so that each half is 2 to 3 inches wide. Cut between bones to make 6-inch pieces. Trim excess fat. Place ribs in heavy resealable bag.

For marinade, combine 1/4 cup soy sauce, hoisin sauce, 2 tablespoons sherry, sugar, ginger, garlic and five-spice powder in small bowl; mix well. Pour over ribs. Seal bag tightly; place in large bowl. Refrigerate 8 hours or overnight, turning bag occasionally.

Preheat oven to 350°F. Line large baking pan with foil. Place ribs on rack in pan, reserving marinade. Bake 30 minutes; turn ribs over. Brush with marinade; continue baking 40 minutes or until ribs are tender when pierced with fork.

For glaze, combine honey, vinegar, remaining 1 tablespoon soy sauce and 1 tablespoon sherry in small bowl; mix well. Brush 1/2 of mixture over ribs. Place under broiler 4 to 6 inches from heat source; broil until ribs are glazed, 2 to 3 minutes. Turn ribs over. Brush with remaining honey mixture. Broil until glazed. Cut into serving-size pieces. Garnish, if desired.

Trim bulbs (white part) from onions; reserve for another use. Trim remaining stems (green part) to 4-inch lengths.

Using sharp scissors, cut each section of green stems lengthwise into very thin strips down to beginning of stems, cutting six to eight strips in each stem section.

Fill large bowl about half full with cold water. Add green onions and ice cubes. Refrigerate until onions curl, about 1 hour; drain.
