Grilled Tuna In Ginger-Cilantro Butter Sauce Recipe

+ Directions : Combine Marinade ingredients. Marinate the tuna in the marinade for 1 hour. Drain and reserve marinade. ADVANCE PREPARATION: In a small noncorrosive saucepan, place the wine, vinegar, ginger, and shallot. Bring to a rapid boil over high heat and cook until just 4 tablespoons remain. Set aside. Cut the butter into 16 pieces and set aside. LAST-MINUTE COOKING: If using a gas barbecue, preheat to medium (350 F). If using charcoal or wood, prepare the fire. When the coals or wood are ash covered, place the fish in a grilling basket. Grill the fish over medium-high heat until it just begins to flake, about 8 minutes. Turn once during barbecuing and brush with the reserved marinade. Transfer the fish to heated dinner plates or a serving platter. Bring the wine-vinegar sauce to a rapid boil over medium-high heat, then add the butter all at once and beat vigorously with a whisk. When just a few lumps of butter remain (about 20 seconds after adding), pour the sauce into a bowl. Stir in the lemon peel, cilantro, pepper, and salt. Taste and adjust seasoning adding more pepper if necessary. Spoon the sauce around the fish and serve at once.
