I went to the Chocolate Museum in Zagreb where I discovered that there are actually four types of chocolate: milk, white, dark and ruby. Feel free to call me a fool if you actually already knew about Ruby chocolate. It was apparently invented in 2004, but it was only revealed to the world in 2017 by a Belgian-Swiss cocoa company. It’s reddish in colour, and sour in taste with unfermented cocoa beans. Have you ever tried it?
