Wash the apricots, stone them, cut into pieces. Peel the mango, cut the flesh from the core, cut into pieces. Peel and finely dice the ginger. Put everything in a large saucepan and puree with the blender. Add the preserving sugar. Bring to the boil with high heat and constant stirring. Let simmer for 3 minutes. Pour hot jam into jars and close immediately. Variation: Instead of apricots, you can also use peaches or nectarines.
