Wash and zest the fresh oranges to collect about 2 tablespoons of zest, then juice the oranges for approximately 3/4 cup of juice.

In a medium saucepan, combine orange juice, 1/4 cup of water, sugar, and corn syrup. Heat over medium heat, stirring until sugar dissolves, then simmer for 10 minutes.

Sprinkle gelatin over 1/4 cup of cold water in a small bowl and let bloom for 5 minutes.

Stir bloomed gelatin into the syrup until dissolved. Add butter and orange zest, stirring until the butter is melted.

Remove from heat and let cool for 1-2 hours at room temperature until thickened.

Pour the mixture into a greased dish or molds. Let set for 1-2 hours at room temperature, then refrigerate for 4-6 hours or overnight.

Once set, remove from molds or dish, and cut into bite-sized pieces. Optionally toss in powdered sugar before serving.
