Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Softened in margarine to build a sweet, savoury base for the soup.
- Potatoes
- Break down during boiling to thicken the soup and give it body.
- Stock
- Cooks the vegetables and provides the main liquid and savoury flavour.
- Soup vegetables
- Carrot, leeks and parsley add sweetness and aroma to the base.
- Bread roll
- Frying cubes in butter turns them crisp and browned for texture.
The step that matters
Pass the soup through a sieve. Straining removes fibrous vegetable pieces and leaves a smooth texture. Sieving while the potatoes are fully tender gives the silkiest result, since undercooked starch stays grainy.
Swap the basil
How well each one fits the dish's main ingredients (onion, carrot, leek, parsley, potato, pepper, bread):
- Thymefits better
- Marjoramfits better
- Celeryfits better
- Basilthe original
Fit is the average pairing score against onion, carrot, leek, parsley, potato, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
