Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White currant juice
Provides the tart fruit flavour and acidity that defines the shrub.
Rum
Acts as the spirit base that preserves the mixture and carries the fruit aroma.
Lump sugar
Sweetens the mixture and balances the sharpness of the currant juice.

The step that matters

Standing overnight and clarifying. Sugar must dissolve fully in the juice and rum during the overnight rest, and straining repeatedly removes fine solids so the shrub becomes clear rather than cloudy.

Swap the white currant

How well each one fits the dish's main ingredients (rum, sugar):

  1. Vanillafits better
  2. Pineapplefits better
  3. Bananafits better
  4. White currantthe original

Fit is the average pairing score against rum, sugar. Candidates are from the same food group and used in at least 100 recipes.
