Fruit-based Kit Kat flavors are very popular in Japan, and they always turn out pretty accurately, in my opinion. This Passion Fruit Kit Kat was purchased by my mom a while back on a trip to Japan, and while I can't really say I eat real passion fruit regularly, it seemed like a fun one to try out.
That being said, if you told me this was a different tropical fruit, I probably would've believed you, haha. The white chocolate was a nice base for the strong fruit smell and flavor, and I think their regular chocolate would've covered that up too much. The Kit Kats themselves were a very pretty pale yellow color which was fun too. In the middle of the bag, it says "Grown Up Sweetness", which is very true - it wasn't overly sweet, more of a sweet/tart mix that adults would probably appreciate more so than little kids. I'm happy I got to try this one!
