Nestle Just Started Selling Pink KitKats Just in time for Valentine's Day, Nestle's brand new KitKats are hitting stores in Japan and South Korea. KitKat Chocolatory Sublime Ruby is made with the "Ruby cacao bean," and features a pink-coloring that is all natural and a natural berry taste as well. Ruby chocolate is a new development in itself, first created by Zurich-based chocolatier Barry Callebaut. Nestle and KitKat is the first company to use Ruby chocolate, throwing it right into production next to Dark, Milk and White chocolate.
