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

What each ingredient does

Brown sugar
Provides sweetness and body, balancing the sharp citrus acidity.
Lemons
Supply acidity and bright citrus flavour that defines the shrub.
Seville oranges
Add acidity and a bitter citrus aroma to the blend.
Whisky or silent spirit
Acts as the preserving alcohol and carries the flavour of the drink.
Porter
Adds roasted malt flavour and colour to the finished drink.

The step that matters

Shake the mixture well every day for a week. Daily shaking keeps the sugar, juice and alcohol evenly mixed, so the sugar dissolves fully and the flavours blend rather than separating in the jar.

Flavor stand-ins for the lemon

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

  1. Vanillabetter flavor fit
  2. Applebetter flavor fit
  3. Figabout as good a flavor fit
  4. Lemonthe original

Fit is the average pairing score against sugar, whisky, orange. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
