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

What each ingredient does

Strong spirits
Dissolves and extracts flavour compounds from the oranges and cloves over time.
Loaf sugar
Adds sweetness and balances the bitterness drawn from the orange peel.
Oranges
Supply aromatic peel oils and juice that give the liqueur its citrus flavour.
Cloves
Add warm, aromatic spice notes that build during steeping.

The step that matters

Cover the jar tightly. A tight seal keeps the alcohol from evaporating and limits air getting in, so the spirit stays at full strength and the flavours extract steadily over the long steep.

Swap the clove

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

  1. Cinnamonfits better
  2. Gingerfits better
  3. Rosemaryfits about as well
  4. Clovethe original

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