Pour the apple juice and the freshly squeezed orange juice into a tall 4 liter saucepan.
Peel, fillet and cut 2 oranges into small pieces, then pour orange liqueur over the fillets and marinate for approx. 1 hour.
Halve the grapefruit and lemon and squeeze. Pour the collected juice into the saucepan and stir in the preserving sugar. Score the vanilla pod with a knife and add to the juice mixture together with the cinnamon stick and leave to rest for 1 hour.
Now add the marinated orange fillets to the juice, mix well and bring to the boil, stirring constantly. Boil the jelly for about 12-15 minutes and after a gelling test, pour it into jam jars that have been rinsed with hot water and close immediately. Place the glasses upside down on a damp kitchen towel and turn them over again after 5 minutes.
To ensure that the pieces of fruit are well distributed, turn the glasses several times while they cool. This amount makes 8 smaller glasses!
