Whole blended limes, sweetened condensed milk & crushed ice
Limonada Suíça (Swiss Lemonade) is ubiquitous at Brazilian churrascarias — the name 'Swiss' is a mystery, as the drink has no Swiss connection whatsoever. The technique of blending the whole lime — skin and all — is the Brazilian innovation. The peel adds a bitter, aromatic complexity that transforms it from a simple creamy drink into something genuinely complex.
5–10 seconds of blending only — the peel releases bitter compounds rapidly. Strain immediately. For a lighter version, use regular milk instead of condensed milk and add more sugar to taste. For a Limonada na Pressão (the simpler version), skip condensed milk and just blend limes, sugar, and ice.
