Score the apricot skin and briefly boil water over it. Rinse in ice water and remove the skin. Halve and stone the apricots. Weigh 900 g of flesh. Mix apricots and jam sugar well in a large pot.
Bring everything to the boil while stirring over high heat and cook for about 8 minutes until it is bubbling. Meanwhile, wash the orange hot, rub dry and cut into slices. Add orange and grated coconut to the jam for the last 2-3 minutes.
(Make a jelly test!) Pour the jam into clean twist-off jars, close them and leave them on the lid for about 5 minutes. Turn the jars over and let them cool down. Jam keeps cool and dark for about 4 months.
