It was first available in 2017 by Barry Callebaut made with ruby cocoa beans.
In 2018, I finally tried Ruby Chocolate in the form of a kitkat where you could taste notes similar to raspberry.
Later on I was lucky enough to discover a coffee shop serving Ruby Chocolate beverage using Callebaut Ruby Chocolate pellets so I got to try the pellets on their own which were sugary with a raspberry tone.
At Lidl they had the Ruby Chocolate bar so I had to give it a try and it was surprisingly nice because the texture of the chocolate was smooth like galaxy with the fruity raspberry aftertaste that I was expecting.
