These amounts are just estimates. I make this drink in my blender. I never measure. You can make it to suit your tastes. The first thing I do is blend the Ice Cubes and Malibu until the ice is fairly crushed. Then I add 1/3 of a can of crushed pineapple, 1/3 of a can of cream of coconut. (You can find this in the mexican section of your grocery store or on the soda isle with the mixers. There are several brands out there) I top off the blender container with ice cream, about three scoops or less. Then you blend it on the highest speed for a few seconds to mix everything. We have also added one banana to this recipe just for a change. Be adventurous, you can't go wrong. Good luck and contact me with any questions or suggestions.
