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 ↓
Vegetable Soup
Ingredients
Directions
Prepare
Prepare the vegetables and cut them into strips about the size of a thick match.
Cook the soup
Melt the butter in a saucepan and fry the vegetables slowly until the butter is absorbed.
Add the boiling water, half of the milk, salt, and pepper, and simmer gently until the vegetables are tender (5 to 10 minutes).
Mix the flour with the remaining milk until smooth, then pour it into the saucepan. Stir and cook for a few minutes, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that softens the vegetables gently and carries their flavour during frying.
- Flour
- Thickens the milk and water into a smooth, lightly body-rich soup.
- Milk
- Adds creaminess and mild sweetness to the soup base.
- Carrots
- Provide sweetness and colour, and soften to a tender texture when simmered.
The step that matters
Adding the flour mixture. Flour must be mixed smoothly with cold milk before it goes into the hot soup, because flour dropped in directly clumps. Stirring while it cooks lets the starch swell and thicken the liquid evenly.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, leek, celery, parsley, butter, flour):
- Parsnipfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, leek, celery, parsley, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
