A v. delayed review of these Japanese Kit Kats, sorry! But chances are none of you were waiting with baited breath anyway, so let's move on, shall we? :o)
These Kit Kats definitely fall into the "Only In Japan" category, both in terms of availability and the willingness of people to actually buy and try them, haha. Like I said about the Japanese Kit Kats before, the majority of the limited edition flavors are based moreso on how unique it would be, especially to give someone as a gift. I mean really, soy sauce? Yeah that stuff you dip your sushi into? Who would've thunken?
When I opened up one of these small packets, I was hit with a strong soy sauce smell (surprise!) mixed with the generic chocolate Kit Kat smell. It was definitely "interesting" to say the least. However, once I bit into the Kit Kat, the soy sauce taste was less evident than what I expected. It tasted more like a salt-based chocolate; if you've had chocolate with sea salt, you know what it's like. I think if you were unaware that this was a Soy Sauce flavor beforehand, you wouldn't exactly be able to pinpoint that that was the flavor.
That being said, I'm not exactly tearing through these packets like I did with the Matcha and Strawberry Milk flavors, and I probably won't be running to get these again anytime soon. However, I'm happy to have had a chance to try them, especially since they aren't available as a permanent flavor. If anyone else wants to try them (and you live near me slash I'll see you at some point) let me know, I have plenty left over, haha.
