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 the vegetables
Peel the onion and wash the carrots, turnip, and leek.
Cut all vegetables into very small dice.
Make the consomme
In a stewpan, combine the vegetables and butter, then season with a little salt, pepper, and sugar.
Cover and cook over low heat for a few minutes, shaking the pan to prevent burning.
Pour in the clear soup and gently boil for about 30 minutes.
Skim off any fat and serve with toasted bread and optional lettuce and sorrel.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness and colour, and a diced texture that holds up in the clear soup.
- Butter
- Carries flavour and gives the vegetables a rich, moist texture as they cook gently.
- Leek
- Adds a mild onion-like aroma and sweetness to the broth.
- Turnip
- Adds a mildly sweet, earthy flavour and firm texture to the diced vegetables.
The step that matters
Cook the vegetables covered over low heat, shaking the pan. Gentle covered heat softens and flavours the vegetables in their own moisture and butter. Too much heat or no shaking lets the diced pieces scorch on the base of the pan, which adds bitter, burnt flavours to the clear soup.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, leek, butter, sugar, pepper, bread):
