  Dissolving stuff in water generally lowers the freezing point – that’s why we spread salt on the roads in cold weather. I would guess that the water preferentially froze out on the outside, leaving the sugar solution (with all the flavour) liquid in the middle. Probably if you had turned the freezer down to a lower setting, so that they froze faster, this wouldn’t have happened. (But please note that I am not an expert on food chemistry!)

  You could also take them out every half hour and give them a mix – this is how you make things like ice creams and sorbets.
