Put the zest and juice from half the orange and lemon in a large saucepan. Halve the peaches, cut the pits into small pieces and place in a blender. Puree finely, if necessary work in two servings.
Put the peach sauce with the sugar in the saucepan and bring to the boil while stirring. Let this simmer for about 45 - 60 minutes, stirring again and again. The best thing to do here is to make a jelly test, the jam will also have the color of honey.
Fill into sterilized jars while still hot and close.
