Double watermelon backed up by sweet watermelon for the main body.
Double apple and dragonfruit for flesh and moisture.
Coolcumber doing triple duties, adding a touch of rind, cool, and wet.
I went with juicy lemon instead of Sicily for the more candy aspect and to add a bit of brightness, but might revise that if the limoncello seems like it would work better.
The slightest bit of Duo lychee, started at 0.75 and it completely overtook the mix, even after a steep it was way too floral. Settled at 0.25 as a nice background flavour.
A bit more sweet and colds than normal cause sorbet, but the sweet could drop either by half or all depending on taste.
