Rhubarb & Custard Sour

Description

The Rhubarb & Custard Sour takes its inspiration from one of Britain’s most beloved retro sweets... the rhubarb and custard boiled sweet. First made popular in the early-to-mid 20th century, these sweets combined the tart, tangy bite of rhubarb with the creamy sweetness of custard for a perfectly balanced flavour. This cocktail transforms that nostalgic combination into a silky, vibrant drink, pairing tart rhubarb gin with smooth vanilla liqueur and a foamy, sour-style finish. It’s a modern mixology homage to a school sweet shop classic.

Ingredients

50 ml Rhubarb Gin
25 ml Vanilla Liqueur (or Licor 43)
25 ml lemon juice

Instructions

Add rhubarb gin, vanilla liqueur, lemon juice, sugar syrup, and egg white to a shaker (no ice).
