Not got any cinnamon syrup? Replace it with sugar syrup or make your own cinnamon syrup. To prepare cinnamon syrup: Take a saucepan and dissolve the sugars (50g light-brown sugar + 150g granulated sugar) in 24cl of water. Break the 4 cinnamon sticks and add them. Let it continue to soak for 50 mins on a low heat. Let it cool and then strain it into one of our empty glass bottles. Store it in a dark place.
