Baked Amaretti Plums with Greek Yoghurt

Cor!!! I've only just finished eating these and looking at the picture makes me want it all over again... Luckily i have another 4 plums in the kitchen but will try to abstain until tomorrow as part of my half-arsed attempt at a more healthy diet. Good lord they are tasty, and I love the dark ruby syrup that oozes from the fruit and mingles with the white yoghurt so prettily...
