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 the carrots, turnips, celery, leeks, and onions into thin shreds about 1 inch long.
Make the soup
In a stewpan, melt the butter over low heat, add the vegetables, salt, and sugar, and stir lightly until they are a very light color.
Transfer the mixture to a soup pot, add enough clear stock for the desired quantity of soup, and bring to a boil.
Remove the pot from heat to let the scum and grease rise to the surface, skimming them off as they appear.
Add the shredded cabbage lettuces, sorrel, tarragon, chervil, and 4 lumps of sugar to the pot.
Allow the soup to simmer until the vegetables are tender, then taste and adjust seasoning before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to gently cook the vegetables in fat, carrying flavor without browning them.
- Carrots
- Add sweetness and color, and hold their shape as thin shreds through simmering.
- Turnips
- Contribute a mild, slightly peppery sweetness and tender body to the broth.
- Leeks
- Build a mild onion-like aroma and sweetness as they soften in butter.
- Cabbage lettuces
- Add tender leafy texture and fresh vegetable flavor when added near the end.
The step that matters
Stir the vegetables in butter only until very light in color. Over-browning the shreds adds bitter, toasted notes and changes the clear, delicate flavor this soup depends on. Low heat and light stirring keep the vegetables sweet and pale.
Swap the onion
