Why it works: Onion and arrowroot match in chemistry and in kitchens. They rank in the top 11% of all ingredient pairs, and cooks put them together in 340 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Westerfield White Soup
Ingredients
Directions
Make the stock
Break the bone of the veal in one or two places and place it in a pot with the cold water.
Once the scum is cleared, add the salt, onions, white peppercorns, mace, and cayenne pepper.
Simmer slowly until the soup reduces by one third, then strain and let it cool.
Finish the soup
Remove the fat and sediment, then reheat the soup in a clean pot.
When boiling, mix in the cream blended with arrowroot and the cooked vermicelli.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of veal
- Releases gelatin and flavour into the water, giving the soup body and a rich mouthfeel.
- Thick cream
- Adds fat and richness, softening the flavour and giving a smooth, velvety texture.
- Arrowroot
- Thickens the soup as it heats, giving it a silky body without clouding it as flour would.
- Fresh vermicelli
- Adds starchy bulk and soft texture to the finished soup.
The step that matters
Clear the scum before adding seasonings. Scum is coagulated protein and impurities that rise during simmering. Skimming it before adding salt and aromatics keeps the stock clear and clean-tasting.
Swap the mace
How well each one fits the dish's main ingredients (veal, onion, pepper, cream, arrowroot):
- Turmericfits better
- Capersfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against veal, onion, pepper, cream, arrowroot. Candidates are from the same food group and used in at least 100 recipes.
