Why it works: Turnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Crecy Soup
Ingredients
Directions
Prepare the soup
Wash and peel the turnip and carrots, then slice them finely.
In a saucepan, melt 2 tablespoons of butter over medium heat.
Add the sliced vegetables and sauté until they are well colored but not browned.
Pour in 3 pints of water and season with salt. Let it simmer for 2 hours.
After cooking, press the mixture through a colander back into the saucepan.
Add hot water to achieve the desired consistency.
Make the croutons and serve
In a frying pan, melt 1 tablespoon of butter and add the bread cubes.
Shake the pan over the heat until the bread cubes are golden brown.
Pour the soup into a tureen and serve with the croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnip
- Gives the soup its body and mild, slightly peppery flavour as it softens during simmering.
- Carrots
- Add sweetness and color, and thicken the soup as they break down when pressed.
- Onion
- Adds aromatic depth and savory flavor when sautéed in butter.
- Butter
- Carries flavor and adds richness to the vegetables during the initial sauté.
The step that matters
Sautéing the sliced vegetables. Cooking them until well colored but not browned builds flavor through gentle caramelization without scorching, which would make the soup taste bitter.
Swap the onion
How well each one fits the dish's main ingredients (turnip, carrot, butter, bread):
- Leekfits better
- Parsnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against turnip, carrot, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
