And if you want to get the Coco Lopez in Uk:
http://www.thedrinkshop.com/products/nlpdetail .php?prodid=3674 online shopping. This is a blend of coconut cream and sugar, so be careful if you try to make the cocktail with just ordinary coconut cream...the above site has all the mixers and blends such as the Funkin' range if you want to try some other things as well...
The coconut cream is the key - and the type of rum you use will also alter the result - a dark rum gives a differnt final colour compared to a white rum, and then off you go and decide which brand rum is better anyway......
