Hello. You stated that you had tried to add more liquor, if that is something that you desire to do, just add a little bit of unflavored gelatin to the liquid. this will help it to set up, but will also take a little longer for it to melt as well. This sounds good. Thanks for sharing.
I have made a similar one but only use orange or lime sherbert. It turned out great and all the guest loved it. Ann
I made this yesterday for tonights dinner. It was simple to make, although a little messy cleaning out the oranges. But in the end, the extra cleanup I had to do for the sprayed orange juice was worth it by far. The Grand Marnier flavour was strong, without being over powering, and could still be enjoyed by those who don't like the tast of alcohol. I'd make this again right now if I hadn't run out of the OJ.
