Jaspar recommends making a batch in their glasses and refreezing them with the straws already in the glass, like the old colonels and their julep freezers...
I disagree with a comment that says "tiki style". Tiki? Just for using an "exotic" liqueur and mint? No, this is a just sour, but a very original sour. Base, Tequila Reposado. Modifier, Licor 43. And the lime. Oh, the mint leaves! I eas acting in a "silent way" and didn't shake, I just poured and stirred not gently at all ;-) It is a very nice sour!!!! Not tiki, but who cares?
