Cut the peel and pith off the oranges and slice them.

Combine orange slices, sugar, honey and cinnamon in a pot and add water so that the orange slices are nearly covered.

Let the pot simmer for 1-2 hours. Avoid stirring. If the orange slices on the top appear dry, gently spoon some of the liquid onto them.

Taste an orange slice with some syrup and adjust with more honey and lemon juice to taste.

Take the pot off the heat when the liquid is much reduced and has a syrupy consistency and the orange slices are tender but still whole.  

Remove the cinnamon sticks. Let the oranges and syrup cool down before serving with greek yoghurt, cake, or ice cream.
