Pomegranate has impressed me when mixed with other fruits, but hadn't tried it with kiwi yet. It's really good with Lime Tahiti or Black Cherry or Bilberry or various combinations, assuming you like pomegranates.
Mango-peach and mango-vienna-cream (like the pudding in Mexican restaurants) are all I've done with mango.
I don't know what goes with passionfruit! Anyone? I have a hard time vaping it plain. It reminds me of the way the slimy seeds in real passionfruit feel, sorta too realistic for me. But there's gotta be another fruit I'd like it with.
Lychee (FA flavor as well as the canned fruit) reminds me of Asian pears. I agree it needs company but haven't found a great one.
Back to the creamy sweets for me....Butterscotch-Meringue-Creamy-Cookies at the moment - a relief after my recent fruit binge.
