Rwandan Tea & Rum Sour with Passionfruit
A coppery, fruit-forward sour built on Rwandan black tea syrup, dark rum, lime and passionfruit — with a non-alcoholic mocktail version that's just as vibrant.
This sour leans into the things that make Rwandan black tea distinctive: its bright, coppery body and gentle honeyed sweetness, which make it a natural partner for the molasses depth of dark rum. Reducing strongly brewed tea into a simple syrup concentrates that character into a cocktail ingredient rather than just a diluting mixer.
Dark or aged rum is the right call here — its caramel and dried-fruit notes echo the tea's own malty undertones, building a drink that feels layered rather than just sweet-and-sour. Passionfruit purée adds the tropical tang that ties the whole thing back to Rwanda's highland gardens, where tea and passionfruit often grow side by side.
Shake hard and shake long: the egg white (or aquafaba, for a vegan version) gives the sour a silky, frothy texture that showcases the drink's amber-pink color beautifully when strained into a coupe glass.
For a non-alcoholic mocktail version, skip the rum entirely and replace it with an extra 30 ml of the Rwandan tea syrup plus a splash of soda water for length — the tea's natural body and brisk finish stand in beautifully for the rum's depth, giving you nearly the same complexity, alcohol-free.
Ingredients
- 45 ml dark or aged rum
- 30 ml Rwandan black tea syrup (recipe below)
- 25 ml fresh lime juice
- 20 ml passionfruit purée (or pulp of 1 fresh passionfruit)
- 1 egg white (or 15 ml aquafaba)
- Ice
- For the tea syrup: 1/2 cup strongly brewed Rwandan black tea + 1/2 cup sugar, simmered until dissolved and cooled
- Lime wheel and a few mint leaves for garnish
How to make it
- 1Make the tea syrup ahead of time: combine the strongly brewed tea and sugar in a small saucepan, simmer gently until the sugar dissolves, then cool completely and refrigerate until needed.
- 2Add the rum, tea syrup, lime juice, passionfruit purée, and egg white (or aquafaba) to a cocktail shaker without ice. Dry shake vigorously for 15 seconds to build the foam.
- 3Add ice and shake again hard for 15–20 seconds until well chilled.
- 4Double-strain into a chilled coupe glass to leave behind any passionfruit seeds and ensure a smooth foam.
- 5Garnish with a lime wheel and a small sprig of mint. For the mocktail, omit the rum, use 60 ml total of tea syrup, and top with a splash of soda water before serving over ice.
