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 into alcohol and carbonation.
Yeast
Ferments the sugars, producing alcohol and carbon dioxide that give the beer its fizz.
Hops
Adds bitterness and aroma that balance the sweetness of the treacle.
Essence of spruce
Gives the beer its characteristic resinous, piney aroma and flavour.

The step that matters

Sealing the cask after fermentation ceases. Sealing too early can trap yeast activity and build pressure, while sealing too late lets the beer oxidise and pick up off-flavours. Waiting until fermentation has stopped keeps the sugar converted and the carbonation controlled.

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.
