Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
A Nice White Soup
Ingredients
Directions
Prepare the broth
Break up the shin of veal and soak it in cold water for 2 hours.
Boil the veal in 4 quarts of water with the onion, mace, pepper, and salt for about 5 hours.
Strain the broth through a sieve and let it cool overnight.
Remove the fat from the cooled broth using a cloth.
Finish the soup
Bring the broth back to a boil, adjusting seasoning as needed.
Mix 2 tablespoons of ground rice with water and stir it into the boiling broth.
Add 1 pint of cream and bring it to a boil again.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal shin
- Gives the broth its rich meaty flavor and body as it simmers for hours.
- Ground rice
- Thickens the boiling broth so the soup becomes smooth and body-rich.
- Cream
- Adds richness and a silky texture that softens the broth's flavor.
The step that matters
Adding the ground rice slurry. Ground rice must be mixed smoothly with water before stirring into boiling broth; otherwise it clumps instead of thickening evenly, because starch granules need to disperse before they gelatinise.
Swap the mace
How well each one fits the dish's main ingredients (veal, onion, pepper, rice, cream):
- Celeryfits better
- Turmericfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against veal, onion, pepper, rice, cream. Candidates are from the same food group and used in at least 100 recipes.
