Why it works: Ginger and raisin are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,242 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Molasses Beer
Ingredients
Directions
Make the beer
In a vessel, combine molasses, yeast, and powdered ginger.
Pour in 2 gallons of scalding hot soft clear water and shake until it ferments.
Add 13 gallons of the same water to fill the cask.
Let the mixture ferment for about 12 hours.
Bottle
Bottle the beer with a raisin or two in each bottle.

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):
- Cinnamonfits better
- Clovefits about as well
- Nutmegfits about as well
- 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.
