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

What each ingredient does

Molasses
Provides sweetness and food for the yeast to ferment 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 molasses.
Sassafras root
Contributes its distinctive aromatic flavour to the brew.

The step that matters

Cool before adding yeast. Yeast is killed or stressed by hot liquid, so the mixture must cool sufficiently before the yeast is stirred in. Adding it while still hot can stop fermentation before it starts.

Swap the allspice

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

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

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