1 Prepare a hot fire in a charcoal grill or preheat a gas or electric grill on high.2 In a small bowl, combine the currants, apple juice, and pepper.3 Allow the currants to marinate until ready to serve.4 Peel the pears and cut them in half lengthwise.5 Use a paring knife or melon baller to remove the core, leaving a gumball-sized-hole.6 Place in a shallow dish and brush all over with the melted butter.7 When ready to grill, brush the grill grate with vegetable oil. Place the pears, cut side up, in a single layer directly over the hot fire.8 Cook just until grill marks appear, about 3 minutes.9 Brush with any butter remaining in the dish, then turn and grill until tender but firm, about 3 to 4 minutes longer.10 Serve warm with a little of the apple juice soaked currants spooned over the top.
