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

What each ingredient does

Molasses
Provides the sugar that yeast ferments, giving the beer its body and dark, sweet flavour.
Yeast
Ferments the sugars into alcohol and carbon dioxide, which makes the beer fizzy.
Raisins
Added to each bottle, they supply a little extra sugar for a second fermentation that carbonates the beer.

The step that matters

Pour in the scalding hot water and shake until it ferments. The water must be hot enough to dissolve the molasses fully, but the mixture must be cooled enough before yeast is added, since very hot liquid kills yeast. Shaking mixes the yeast evenly through the liquid so fermentation starts uniformly.

Swap the ginger

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

  1. Cinnamonfits better
  2. Clovefits about as well
  3. Nutmegfits about as well
  4. Gingerthe original

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