1. Bring first 6 ingredients and 1/2 cup water to a boil over medium-high heat. Boil, stirring often, 1 minute. Remove from heat, and let stand 30 minutes.
2. Meanwhile, peel oranges, next 3 ingredients, and, if desired, kumquats. Cut away bitter white pith. Cut each fruit into thin rounds. Arrange on a serving platter, and sprinkle with pomegranate seeds.
3. Pour honey mixture through a fine wire-mesh strainer, discarding solids. Drizzle fruit with desired amount of spiced honey; reserve remaining for another use (such as flavoring iced tea). Top with a drizzle of olive oil, a handful of mint leaves, and sea salt.
*Pink or red peppercorns may be substituted.
Note: Salad may be made up to a day ahead. Prepare as directed; cover and chill up to 24 hours.
