Why it works: Corn and lemon are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,927 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Corn Beer
Ingredients
Directions
Make the mixture
Combine cold water, corn, and molasses in a keg.
Ferment
Seal the keg tightly and let it ferment for 2 to 3 days.
If the mixture becomes too sour, add more molasses and water in the same proportions.
Flavor
If desired, flavor with oils of spruce or lemon by adding 1 or 2 quarts of boiling water to the oils.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn
- Supplies starches and sugars that yeast and bacteria ferment into alcohol and acidity.
- Molasses
- Provides fermentable sugar that feeds the fermentation and adds dark, sweet flavour.
- Cold water
- Forms the liquid base that dissolves the sugars and carries the fermentation.
The step that matters
Keeping the ferment from turning too sour. Fermentation continues as sugars convert to acids. If the mixture becomes too sour, adding more molasses and water in the same proportions dilutes the acid and supplies fresh sugar to keep the brew balanced.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (corn, molasses):

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