Prep Oranges: Wash the fresh oranges thoroughly, zest them avoiding the white pith, and juice until you have about 3/4 cup of juice.

Cook Syrup: In a medium saucepan, combine orange juice, 1/2 cup of water, sugar, and corn syrup. Stir over medium heat until sugar dissolves. Simmer for about 10 minutes until thickened.

Bloom Gelatin: In a small bowl, sprinkle gelatin over 1/4 cup of cold water, let sit for about 5 minutes.

Combine Mixtures: Stir the bloomed gelatin into the syrup until dissolved. Add butter and orange zest, and cook for another 5 minutes on low heat.

Cool Mixture: Transfer mixture to a bowl, cool at room temperature for 1 to 2 hours.

Set Candy: Pour mixture into a greased dish or molds, cool at room temperature for 1 to 2 hours, then refrigerate for 4 to 6 hours.

Cut Candy: Once set, remove from the dish and cut into desired shapes; toss in powdered sugar if desired.
