Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Prepare
Wash, scrape, and slice the carrots.
Wash, peel, and slice the turnips and onions.
Wash and quarter the celery and leeks.
Wash and quarter the lettuce and cabbage.
Make the soup
Melt ½ cup of butter in a saucepan and add all the vegetables.
Cook the vegetables over medium heat for 10 minutes, stirring occasionally.
Add 3 quarts of cold water, bring to a boil, skim the surface, then reduce heat and simmer for 1 hour.

Return the puree to the saucepan and warm it over low heat.
Serve the puree in a hot soup tureen or basin, with toasted or fried bread cut into dice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat that carries flavor and gives the puree a smooth mouthfeel.
- Carrots
- Contribute natural sweetness, body, and color to the puree.
- Onions
- Release aromatic compounds during cooking, building a savory base flavor.
- Celery
- Adds a fresh, savory aroma that rounds out the vegetable flavor.
- Leeks
- Provide a mild onion-like flavor and soft body once simmered and strained.
- Turnips
- Add body to the puree and a mild, slightly peppery flavor.
The step that matters
Pass the contents through a fine sieve. Cooked vegetables are soft and fibrous, so pressing them firmly through a fine sieve with a wooden spoon breaks them down and removes stringy bits, giving the puree its smooth texture.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, celery, leek, lettuce, cabbage, butter):
- Parsnipfits better
- Beetrootfits better
- Endivefits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, celery, leek, lettuce, cabbage, butter. Candidates are from the same food group and used in at least 100 recipes.
