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 ↓
White Vegetable Soup
Ingredients
Directions
Prepare the vegetables
Prepare the carrot, turnip, onion, and potatoes, cutting them into very fine dice.
Melt the dripping in a pot.
Add the diced vegetables and sweat for about 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during simmering to give the soup body and a thick, smooth texture.
- Sago
- Becomes clear and thickens the soup as its starch gelatinises during simmering.
- Milk
- Adds richness and a mild creamy flavour to the soup.
- Dripping or margarine
- Provides fat for sweating the vegetables, carrying flavour and softening them.
- Onions
- Sweat in fat to build a sweet, savoury base for the soup.
The step that matters
Simmering the sago until clear. Sago must be simmered long enough for its starch to fully cook and turn clear and transparent. Undercooked sago stays cloudy and tastes raw, and it can clump if added without being mixed smoothly with water first.

Fit is the average pairing score against potato, carrot, turnip, pepper, milk, parsley. Candidates are from the same food group and used in at least 100 recipes.
