Prepare the syrup in a pan by boiling sugar, water, cassia, cardamom pods and cloves. Stir continuously until the sugar gets dissolves. Simmer for 2 minutes and remove it from heat. Add the orange and lime juice. Leave to cool and infuse while preparing the fruits.
Peel and remove the seeds from the melons and cut the flesh into neat slices. Cut the guavas in half, scoop out the seeds, then peel and slice flesh neatly. Cut the nectarines into slices and hull and slice the straw berries. Arrange the slices of fruit attractively on 6 serving plates. Strain the cooled syrup and spoon over the sliced fruits. Sprinkle with a little toasted coconut. If needed it can also be served with strained thick yogurt.
