Why Do NZ SB's Taste That Way?

[quijote]

Here's another fruit to throw into the loop: Passion Fruit! I bought a real Passion Fruit this weekend, and minutes ago sliced it open and scooped out the flesh and seeds. So far, the Passion Fruit aroma is the closest I've come to the NZSB-style aroma. I haven't been able to find a real guava around here, though, so this eureka is tentative....

If you get a chance to try a fresh passion fruit (and not jarred or canned), do so; I can now see why it's used so much as a descriptor.
