Why it works: Carrot and tomato match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,606 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Carrot Soup
Ingredients
Directions
Prepare
Scrape and finely grate the carrots; slice the tomato if using.
Make the soup
Heat the broth and season it with fried onions in butter, mace, and salt.
Add the grated carrots to the broth, cover, and simmer for 2 to 3 hours.
Pass the mixture through a fine sieve to create a smooth puree.
If desired, boil the soup and add cream or milk and egg yolks for richness.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide the main body, sweetness and colour of the soup as they break down during simmering.
- Broth
- Forms the liquid base that carries the flavour and extracts the carrot's sweetness.
- Onions
- Fried in butter first, they add savoury depth and aroma to the base.
- Cream or milk
- Adds fat and richness, giving the soup a softer, smoother mouthfeel.
- Egg yolks
- Enrich and thicken the soup slightly, adding body and a silky texture.
The step that matters
Adding the egg yolks. Egg yolks can curdle or scramble if they meet a boiling liquid directly. Whisking them with a little warm soup first and adding them off the heat helps keep the soup smooth.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (carrot, onion, butter, mace, meat, cream, egg):
- Potatofits better
- Leekfits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against carrot, onion, butter, mace, meat, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
