Caiproska is an improvisation on the Bazilian national cockatil - Caiprinhia and it has no mint in it. Allow me to differentiate these three drinks and for once clear the air around these 3 classic muddled drinks. These are classic recipes and there may be variations available around the world but the DNA wont change so much.
Mojito - Orginated in Cuba
Mint & Lime muddled with white sugar, load with ice, slop in White Rum & top it with a splash of soda. Served in a long glass
Caiprinhia - Orginated in Brazil
Lime muddled with castor sugar, load with crushed ice, add 60 ml Cachaca (Brazilian white rum made from Sugar cane juice - much sweeter than regular white rum). No soda, no mint please. Served in rocks glass or a small glass as there is no soda and mostly alcohol & ice.
Caiproska - Improvisation of Caiprinhia
Same as Caiprinhia except that Vodka replaces Cachaca. No mint, no soda again.
