Pour the cranberry-raspberry juice into a large heatproof measuring jug and heat it until it's hot but not boiling - you can do this in the microwave or on the stovetop.
02 -
Sprinkle the unflavored gelatin evenly over the hot juice and let it sit for about 5 minutes to bloom. Then whisk it until the gelatin is completely dissolved and there are no lumps.
03 -
Add the triple sec and 120 ml (about 1/2 cup) of the reserved mandarin orange syrup to the dissolved gelatin mixture. Pour in the red sparkling wine until you reach the 950 ml mark (about 4 cups total liquid). Stir everything gently to combine. If there's any foam on the surface, skim it off. Set the mixture aside at room temperature while you prep the fruit.

Line up forty 60 ml shot cups on a baking tray. Put 2 to 3 pieces of mandarin orange and several fresh raspberries in the bottom of each cup.
05 -
Peel, core, and dice the apples into small cubes. Toss them with the lemon juice to keep them from turning brown. Divide the diced apples evenly among all the cups.
06 -
Carefully pour the wine-gelatin mixture into each cup, dividing it equally among all 40 portions. The fruit will float up a bit, and that's perfect.

Transfer the whole tray of cups to the refrigerator and chill for at least 2 hours, or until the jello is completely set and firm. Serve cold and enjoy!
