Why it works: Cinnamon and lemon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Beer Soup
Ingredients
Directions
Mix the beer with water in a pot.
Boil the mixture with sugar and grated rye bread.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beer
- Forms the liquid base and gives the soup its characteristic malty flavor.
- Stale rye bread
- Thickens the soup as it boils, adding body and a grainy flavor.
- Sugar
- Adds sweetness that balances the sourness of the lemon juice.
- Lemon juice
- Adds acidity that brightens the soup and balances the sweetness.
The step that matters
Boiling the bread with the beer and sugar. Bread must be fully softened and dissolved into the liquid as it boils, or the soup stays gritty. Keeping the boil gentle prevents the thin liquid from scorching on the bottom of the pot.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (beer, sugar, rye, bread, cinnamon, lemon):
- Vanillafits better
- Orangefits better
- Figfits better
- Currantthe original
Fit is the average pairing score against beer, sugar, rye, bread, cinnamon, lemon. Candidates are from the same food group and used in at least 100 recipes.
