Preheat oven to 450 degrees. Oil a jellyroll pan. Bring the satsuma orange juice to a boil over medium high heat. Cook until reduced to about 1/3 cup. Save 4 tsp of the juice for later. Arrange the endive in a single layer on the prepared jellyroll pan. Brush each endive with the satsuma juice. Sprinkle with 1/4 tsp salt and 1/4 tsp pepper. Bake until golden, about 10 minutes. Combine 1 tbsp olive oil, remaining salt and pepper, chives, reserved juice, coriander, honey, lemon juice, and satsuma zest, and whisk thoroughly. Place the roasted endives on a platter, top with the satsuma sections, and drizzle with the glaze. Enjoy!
