Begin by cutting the orange into quarters and then slice the quarters. Halve the lemon and then slice into quarters.
Stud the small orange with the cloves, then put all the ingredients into a large saucepan and add 1¾ pints (1 litre) of cold water. Stir together and simmer for 15-20 minutes to allow the flavours to infuse.
Taste before serving and add more honey or sugar, if needed.
Ladle into mugs or heatproof glasses, remembering to remove the cinnamon stick and star anise.
