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 ↓
White Soup
Ingredients
Directions
Prepare the broth
Soak the shin of veal in cold water for 2 hours.
Boil the veal in 4 quarts of water with the onion, mace, pepper, and salt for 5 hours.
Strain the broth through a sieve and let it cool overnight.
Remove the fat from the cooled broth using a cloth.
Thicken and finish
Bring the broth back to a boil.
Mix the ground rice with a little water and stir it into the boiling broth.
Add the heavy 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
- Ground rice
- Thickens the broth as its starch swells in the hot liquid, giving it body.
- Heavy cream
- Adds richness and a smooth, creamy mouthfeel to the broth.
- Shin of veal
- Releases gelatin and flavor into the water during long simmering, giving the broth body.
The step that matters
Stirring in the ground rice. Ground rice must be mixed smoothly with a little cold water first and stirred into boiling broth. Added dry or lumpy, it clumps and does not thicken evenly, since starch only swells and thickens properly when dispersed in liquid and heated.
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.
