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
Cut all vegetables into very fine, narrow strips, using equal quantities of each.
Cook
In a stewpan, combine the vegetables with a good lump of butter, a little sugar, and coarse sea salt.
Cover and let them stew for a few minutes.
Add broth and boil until all vegetables are thoroughly cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provides bulk, sweetness and colour to the soup as the strips cook through.
- Butter
- Adds fat and richness, and helps the vegetables stew gently in the pan.
- Broth
- Supplies the liquid in which the vegetables finish cooking into a soup.
- Potatoes
- Softens as it cooks, adding body and starch that thickens the soup slightly.
The step that matters
Stewing before adding broth. Covering the vegetables and stewing them gently in butter draws out moisture and softens them evenly, so they cook through properly once the broth is added and boiled.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, parsnip, cabbage, celery, leek, potato):
- Beetrootfits better
- Lettucefits better
- Jerusalem artichokefits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, parsnip, cabbage, celery, leek, potato. Candidates are from the same food group and used in at least 100 recipes.
