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 outer rind of the carrots.
If using, slice the tomato and add it to the grated carrots.
Make the soup
Heat the broth in a pot and season with fried onions in butter, mace, and salt.
Add the grated carrots to the broth, cover, and let it simmer for 2 to 3 hours.
Once soft, strain the mixture through a fine sieve until smooth.
Add cream or the milk and egg yolks to the soup.
Heat gently.

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 color of the soup as they soften.
- Broth
- Forms the liquid base that carries the flavor and cooks the carrots.
- Onions
- Fried in butter, they add savory depth and aroma to the base.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
The step that matters
Simmering until the carrots are fully soft. Carrots must be fully tender before straining; undercooked pieces stay fibrous and can't be pushed through a fine sieve into a smooth texture.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (carrot, onion, beef, butter, mace, cream):
- Potatofits better
- Leekfits better
- Turnipfits better
- Tomatothe original
Fit is the average pairing score against carrot, onion, beef, butter, mace, cream. Candidates are from the same food group and used in at least 100 recipes.
