Preparation

• In a small bowl. mix the chiles, fish sauce, water, lemongrass, and brown sugar. Pit each mango by holding it with the narrow side up and cutting through on each side of the large, flat, central pit to give you two big pitless pieces. With a sharp knife, peel these pieces and cut them into spears about 3 inches long and 1 inch thick. Peel the skin from the remaining pit section and cut the flesh near the pit into spears, if possible. (You can peel the mangos before slicing, but they become quite slippery.)
• Pour the marinade over the mangos and toss to coat. Let marinate for at least 20 minutes but not more than 1 hour. Have ready a moderately hot fire. Grill the fruit to soften its texture, letting it brown slightly, about 2 minutes per side. When cooked, transfer it to a platter, pour any remaining marinade over the mangos, and sprinkle with the cilantro, mint, and basil. Serve warm as an appetizer with your favorite beer.
