It's good to see you back on, tancowgirl!
I'll have to dig through some of my recipes later but the Lemon Raspberry Bombes that I posted here REC--Lemon-Raspberry Ice Cream Bombes (tnt)
may be of interest to you.
My only concern would be freezing anything for 2 weeks prior to serving. If they're dished individually in advanced and then wrapped and frozen I'd worry about the consistency getting tacky or gummy.
Do they have to be dished that far ahead? You could make several large pans of granita and if sealed well that could keep for 2 weeks. But that would have to be plated and served at the same time. Let me think about it for you....
