I made this drink according to the recipe here, and it came out well. The reduced cream of coconut is what attracted me to this recipe, because I used homemade cream of coconut, and the process of making my own let me know exactly how much sugar is in that stuff. The result was very pleasant. Of course, the most important quality of any blue curacao drink is that it should be blue, but this one is also pretty tasty. It packs a little bit of a punch though, with 45ml of rum and 40ml blue curacao.
