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

What each ingredient does

Treacle
Provides sugar that the yeast ferments, and adds sweetness and dark color.
Yeast
Ferments the sugars, producing alcohol and carbon dioxide that gives the beer its character.
Hops
Add bitterness that balances the sweetness and help preserve the beer.
Essence of spruce
Gives the beer its distinctive resinous, aromatic flavor.

The step that matters

Sealing the cask. Seal the cask only after fermentation has truly stopped. Sealing too early can trap carbon dioxide and build pressure, while sealing too late exposes the beer to air, which can spoil it.

Swap the allspice

How well each one fits the dish's main ingredients (ginger, hops):

  1. Cinnamonfits better
  2. Clovefits better
  3. Turmericfits better
  4. Allspicethe original

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