The good news: a new butter-flavored Kit Kat will be unveiled next month. The bad news (unless you happen to live in the vicinity): it will only be available in one store in the northern Japanese city of Sapporo, which lies on the island of Hokkaido.
The rich new buttery flavor was the winner of a contest organized by the Tsuji Group culinary school, which sought to highlight an ingredient local to the region. Milk and butter are among the island’s main claims to fame — luckily, in this case, beating out other Hokkaido specialties like sea urchin and salmon.
The butter-flavor chocolate-covered wafers will be sold at the Sapporo branch of Chocolatory, a Kit Kat specialty store, in four-packs for $3.36 or 12-packs for $10.20.
Kit Kats enjoy immense popularity in Japan, partly because parent company Nestle has been wowing consumers with its limited edition local flavors — like special Sakura Green Tea Kit Kats (made with green tea, white chocolate and edible cherry-blossom leaves), Strawberry Cheesecake and (yes) Wasabi.
The butter-flavored Kit Kat will be available from March 7. If you have friends in Sapporo, now’s the time to start calling in a few favors.
