In any case, this recipe makes about 4 litres/quarts of slush so a 4.5 or 5 litre/quart container will be required.
A 4 ounce serving of this slush with a 2 ounce splash of soda water per serving works out to a cocktail that is about 5% alcohol/volume.
This recipe is also easily halved for a smaller batch of 2 litres, using a 375 ml flask of rum.
