What's your favorite, easily-to-make, rum-based cocktail?

Question

I'm considering a rum purchase tonight. I like mojitos, but perhaps there are some other good drinks I can make with minimal additional hassle..?

Answer 1

I really like rum, pineapple juice, and orange juice.  For something a little sweeter, try rum, orange juice, and cherry juice.

Answer 2

Simple: Rum & Coke

Or try a Northern Michigan Drink called a "Duck f**t"  1/3 of Baily's; 1/3 of Kahlua; 1/3 of Crown Royal .....OOPS   pour it in this order first Kahlua, Baily's and then Crown Royal straight up or on the rocks.........it's a great after dinner drink.
