I often do something like this when we have guests - it goes really well with a good chocolate cake, or a polenta cake.
about 90g sugar
flavourings: either long strips of citrus zest; a vanilla pod; lemon grass; cinnamon stick; fresh grated ginger
6 peaches, or 12 plums or whatever
try 1 part sugar to 4 parts water. Dissolve it over a low heat, and taste for sweetness, and adjust. Then add flavourings and bring to the boil.
then the fruit - cut them in half, stone them if you can. Poach for - oh - 15 minutes or so. Then remove, and boil the syrup down a bit.
