For the pomegranate satsuma jelly, scoop out the pomegranate seeds, place in a small saucepan and bring to a boil with about 100 ml of water.
Using a cocktail masher, crush the seeds so that all the juice can escape. Strain the pulp through a sieve. Squeeze the satsumas and half the lemon. Mix the juice of the citrus fruits with the pomegranate juice.
It should give a volume of about 600 ml, if necessary adjust the amount of jelling sugar (for 100ml of juice use 100ml of jelling sugar 1:1). Mix the juice with the jam sugar in a pot and let it stand overnight.
The next day, bring the mixture to a boil and simmer for 4-6 minutes until bubbly and the jelly test is positive. Pour the jelly into sterile twist-off jars.
