Paulmaretto Sour – Pandan Liqueur Cocktail by Paul van Os & Egon Robbe

The Paulmaretto Sour is a refreshing pandan liqueur cocktail created by bartenders Paul van Os and Egon Robbe at Ron Gastrobar Indonesia in Laren, the Netherlands. Inspired by tropical flavours and classic sour cocktails, this drink combines the aromatic sweetness of pandan with the nutty character of amaretto.

Made with Bandoeng’22 pandan liqueur, the cocktail develops a vibrant tropical aroma and a subtle emerald-green character. Pandan is often described as the “vanilla of Asia”, bringing warm notes of vanilla, coconut and toasted nuts.

Balanced with fresh lime juice and egg white, the Paulmaretto Sour is a smooth and elegant cocktail that pairs beautifully with Indonesian dishes and a traditional rice table.
