Why it works: Carrot and onion are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Make the stock
Combine veal, ham, water, herbs, carrots, onions, mace, peppercorns, and salt in a large pot.
Simmer for 5 hours.
Add the chickens and cook for an additional 1 to 1½ hours.
Strain the stock and let it cool.
Skim off any fat.
Make the soup
In a small portion of boiling stock, steep the bread for a few minutes.
Drain the bread.
Pound the bread with the chicken until well blended.
Gradually mix in the stock until smooth.
Pass the mixture through a sieve into a clean pot.
Heat the mixture.
Stir in 1 to 1½ pints of boiling cream.
If the soup is not thick enough, mix 1½ oz of arrow‑root with cold milk or stock.
Add the mixture to the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Long simmering releases gelatin and flavour, giving the stock body and a rich base.
- Chicken
- Adds savoury depth and body to the stock and is pounded into the soup for texture.
- Light stale bread
- Thickens the soup as it breaks down, giving a smooth, velvety body.
- Cream
- Adds richness and a smooth, silky mouthfeel to the finished soup.
- Arrow-root
- Acts as a starch thickener to firm up the soup if it is still thin.
The step that matters
Thickening with arrow-root. Starch must be mixed smoothly with cold liquid before adding it, because dropped into hot soup it clumps. Starch thickens only when heated, so the soup should be brought back to a simmer after it is added.
Swap the mace
How well each one fits the dish's main ingredients (veal, ham, carrot, onion, chicken, bread, cream):
- Celeryfits better
- Garlicfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against veal, ham, carrot, onion, chicken, bread, cream. Candidates are from the same food group and used in at least 100 recipes.
