Slice 5 blood oranges in half and carefully remove the fruit portion to make orange peel “cups.”
Juice enough Blood Orange (10) to yield 1 cup of blood orange juice. You will probably need approximately 10 oranges to get enough juice. If you don’t have enough, you can simply add in some regular store-bought orange juice.
Strain juice to remove solids and place in a small saucepan. Sprinkle with Gelatin Powder (1 1/2 package) and Granulated Sugar (1 tablespoon), allow gelatin to soak for a minute or two. Heat over medium, stirring until the sugar and gelatin dissolved.
Stir in Champagne (3/4 cup) and Grand Marnier (1/4 cup) and pour into orange halves that have been secured in a muffin tin.
Allow to set several hours or overnight.
Slice into wedges and serve!
