Why it works: Cinnamon and pepper match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and 4,890 recipes mention both. Both carry methyl cinnamate, which smells strawberry. The science ↓
Vegetarian Cookery
Ingredients
Directions
Prepare
Sieve the lentils, then add a crust of stale bread.
Let the whole boil, and skim off any dark film that rises to the surface.
Boil for about four hours, or until the lentils are thoroughly soft.
Strain and finish
Strain the soup through a wire sieve.
Rub the whole contents through the wire sieve with the soup.
Boil the soup up again.
If made from green lentils, color the soup green with spinach extract; if made from red lentils, color it with a few drops of Parisian essence.
While warming, stir constantly to prevent the lentil powder from settling and burning.
Serve
Serve by stirring the contents of the soup-tureen with the soup-ladle before each help.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils (in the method)
- Break down during long boiling to thicken the soup and give it body.
- Stock
- Forms the liquid base that carries the flavour of the soup.
- Onions
- Soften during cooking, adding sweetness and aroma to the soup.
- Milk
- Adds richness and a creamy mouthfeel to the soup.
The step that matters
Stirring constantly while warming. The lentil powder is heavy and settles to the bottom of the pan, where it can scorch. Constant stirring keeps the particles suspended and spreads heat evenly, so the soup stays smooth and does not taste burnt.

Fit is the average pairing score against milk, sherry, egg, cinnamon, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
