How can I Mix frozen can Juice with Bacardi Rum?
If it were me I would make the juice first, as directed, like 3 cans of water to one can concentrate sort of thing. Then in a blender add 1-2 oz of Rum per drink, to 6-8 oz of juice and add enough ice that it up to the top of the liquid, not floating and not more ice than liquid and blend. If you don’t feel like making the juice, and you make it from concentrate you will be making more than a blender full for sure. I would use like a couple tablespoon scoops of concentrate to 1 oz of Rum, a cup of water, and 1 cup of ice per drink. Try it and see what works.
