Oh, how things can change in the space of 24 hours for a chocolate-lover.

While yesterday we celebrated the Malteaser Teaser going it alone, today we're being forced to consider the unlikely combination of chocolate… and sushi.

But after research aplenty, we've decided this may actually be something we can get on board with because – for the most part – these delicacies are actually sweet.

The idea, which started as an April Fool's joke last year, gained momentum over recent months, and resulted in a speciality store in Japan creating and serving the KitKat sushi delicacy.

So for those of you still reading, the delicacies will come in three flavours;  Maguro, Tamago and Uni.

According to reports, Maguro is raspberry flavoured Kit Kat on puffed rice covered with white chocolate – definitely something we'd try.

And then it gets a little fishier…

Uni has both melon and mascarpone cheese-flavoured Kit Kats wrapped in seaweed while Tamago is pumpkin pudding-flavoured, served on puffed rice covered in white chocolate and wrapped with seaweed.

Oh, and all three varieties have a hint of wasabi.

Perhaps given the unlikely combinations, the delicacies will only be available at Tokyo's newest KitKat Chocolatory shop between February 2 and 4 this year.

Maybe it'll catch on…
