1. Preheat oven to 450Â°F. Use your hands to flatten hen quarters somewhat. Season lightly with salt and generously with pepper. Place in a shallow roasting pan, skin side up. Roast 10 minutes.
2. Meanwhile, make glaze. In a small saucepan, heat together mustard, preserves, oil, and lemon juice. After hens have roasted 10 minutes, turn and brush with some of glaze. Roast 10 minutes. Turn again and brush with glaze. Roast until juices run clear when pricked with a knife tip, about 15 minutes longer.
