Why This Works
Mango and chile is one of the oldest flavor pairings in Mexico — the fruit's honeyed sweetness and the pepper's heat are opposites that sharpen each other. Shaking fresh jalapeño slices, rather than infusing, gives a greener, fresher heat that sits on top of the drink instead of soaking through it.
The Tajín rim ties the whole build together: chile, lime, and salt in one coating, echoing every element already in the glass. Mango purée also brings serious body — this drink has a plush, almost smoothie-like weight that plain juice margaritas can't match.
The Alcohol-Free Swap
Alcohol-free tequila keeps the drink anchored — mango's richness needs the agave earthiness underneath to stay cocktail-shaped.
