1 Gently heat the orange juice with the sugar in a pan until the sugar dissolves (but do not boil, as the gelatine will be less effective).
2 Soak all the gelatine leaves in a bowlful of cold water for about 5 minutes, or until they are soft and pliable. Remove from the soaking water and squeeze out any excess water with your hands. Stir into the warm blood orange juice.
3 Pour the blood orange juice through a sieve into a jug and tip half of it into a glass bowl. Place into the fridge to just set. This can take up to an hour depending on the temperature of your fridge.
4 While your jelly is setting, prepare your blood oranges by either segmenting them or cutting them across into pin wheels. Whatever method you use, the orange has to have its outer skin and pith removed. This can be done easily by cutting across the top and bottom of the orange, and cutting away the skin and pith by using downward strokes. (Any other fruit pieces could be used.)
5 Remove the bowl from the fridge and arrange the orange pieces on top of the set jelly before topping up with the rest of the blood orange juice. Return to the fridge to set.
6 You can serve up the jelly straight from the bowl and it will be utterly delicious. Don't forget the cream.
