1. In a medium saucepan, combine milk, cream, sugar and pepper. Bring to a boil. Immediately remove from heat. Meanwhile, in a medium bowl, whisk egg yolks until light in color.
2. Slowly stir the hot cream mixture into the beaten egg yolks. Place mixture over a large bowl of ice to cool, stirring occasionally.
3. Stir orange blossom water into cooled cream mixture. Cover and refrigerate until cold.
4. Freeze cold cream mixture in an ice cream maker according to manufacturer’s instructions. If desired, transfer to a freezer-safe container and freeze until ready to serve.
5. Preheat grill for direct cooking over medium heat. Meanwhile, stand a mango on a cutting board with stem side down. Using a sharp knife, start at the top and cut downward slightly away from the center and next to one side of the pit to give you one mango “cheek.” Repeat with other side and remaining 2 mangoes. Score the flesh of the mangoes in a diamond pattern, cutting to, but not through the skin. Pop the flesh by holding the skin side and pushing up.
6. Brush the flesh of mango halves with oil. Grill, cut sides down, for 1 to 2 minutes or until slightly charred.
7. To serve, plate mangoes on individual plates or bowls; add a scoop of ice cream to each and drizzle with Raspberry Coulis, if desired.
