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 ↓
Julienne Soup
Ingredients
Directions
Prepare the vegetables
Wash and dry the vegetables, then cut them into thin shreds, no longer than 1 inch.
In a stewpan, melt the butter over low heat and add the vegetable shreds and a pinch of sugar.
Stir until slightly browned.
Simmer the soup
Pour in the clear stock and simmer gently for 1 hour, or until the vegetables are tender.
Skim off any scum and grease.
Half an hour before serving, add the sugar, salt, pepper, cabbage lettuces, sorrel, and chervil, which should be cut similarly and briefly immersed in boiling water.
Boil for an additional 30 minutes.
Skim carefully.
Serve
Serve hot.
Serve with fried bread cubes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness, colour and body as the main shredded vegetable in the soup.
- Butter
- Adds richness and, when the shreds are gently browned, a deeper savoury flavour.
- Clear stock
- Forms the liquid base and carries the flavour of the vegetables.
- Cabbage lettuces
- Add tender leafy texture and a mild, fresh vegetable flavour near the end of cooking.
- Sorrel
- Adds a bright, lemony acidity that lifts the flavour of the soup.
- Chervil
- Adds a delicate, fresh herbal aroma at the end of cooking.
The step that matters
Browning the shredded vegetables in butter. Stirring the vegetables in butter until only slightly browned develops savoury, caramelised flavour through the Maillard reaction. Browning too far, or too quickly on high heat, can turn them bitter and colour the clear stock.
Swap the onion

Fit is the average pairing score against carrot, turnip, celery, leek, butter, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
