Jamaican Juice Recipe
2 oz Jamaican Rum
5 oz Grapefruit juice
3 Ice cubes
You must mix your drink with these amounts otherwise you'll taste an extremely bitter drink or a very disgusting puke creater. Before you pour the drink, you must put the ice cubes in the mason jar.
Also, if you would like a sweeter taste, feel free to add a pinch or two of sugar.
