This restaurant-inspired dessert combines crisp and creamy textures, warm and icy temperatures and the distinctive flavors of black rum, charred oranges and aromatic allspice.
For the Charred Orange Sorbet, grate orange peel. Set aside. Remove white pith from orange. Cut orange crosswise into 6 slices. Place on foil-lined baking pan. Sprinkle with 2 tablespoons of the sugar. Broil 4 to 6 inches from heat 7 to 8 minutes or until lightly charred. Cool orange slices then coarsely chop.
Place remaining 2/3 cup sugar and reserved grated peel in blender container; cover. Blend on high speed until well mixed. Add orange juice, coconut milk and half-and-half. Blend until sugar is dissolved. Pour into medium bowl. Stir in chopped orange.
Refrigerate 2 hours or until well chilled. Pour into an ice cream maker. Freeze according to manufacturer's directions.
For the Spiced Cookie Bars, preheat oven to 375°F. Mix flour and allspice in medium bowl. Set aside. Beat butter and sugars in large bowl with electric mixer on medium speed until light and fluffy.
