Why it works: Carrot and allspice match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,021 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the gelatinous meat and jelly that give the soup its body and richness.
- Browned flour
- Thickens the soup into a smooth body while adding a toasted, roasted flavour.
- Butter
- Carries the flavour of the aromatics and helps form the browned roux that thickens the soup.
- Strained tomatoes
- Adds acidity and savoury depth that give the soup its characteristic colour and tang.
- Brown sherry
- Adds a fortified wine sweetness and aroma to the finished soup.
- Lemon juice
- Adds brightness and acidity that balance the rich, gelatinous broth.
The step that matters
Thicken the soup with the browned roux. Flour must be cooked into the fat and stirred smoothly into the hot liquid, or it forms lumps and leaves a raw, pasty taste. Bringing the soup to a boil afterward lets the starch fully swell and thicken.
Swap the onion
How well each one fits the dish's main ingredients (tomato, butter, flour, carrot, allspice, lemon, sherry):
- Capsicumfits better
- Parsnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against tomato, butter, flour, carrot, allspice, lemon, sherry. Candidates are from the same food group and used in at least 100 recipes.
