This was definitely the surprise package in our trip! It was extremely informing and very interactive with the guides and the chocolate itself. You're able to taste the Cocoa beans in every stage of the process. The differences in taste and smell are pretty amazing in each different stage of processing the Cocoa bean.
Of course the best part is being able to taste the chocolate and mix it with sugar which makes it delicious! The guides encourage you to be creative in mixing different spices with the chocolate to see what flavors mix well. Overall very entertaining, and even if you're not a huge chocolate lover you'll still really enjoy this. I would encourage to do this activity at the beginning of your trip as it will be most meaningful to you then.
