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
Cut the carrots, turnips, celery, leeks, and onions into thin shreds about an inch long.
Make the soup
In a stewpan, melt the butter over low heat, add the vegetables, salt, and sugar, and fry until lightly colored.
Transfer the mixture to a soup pot and add enough clear stock for the desired quantity of soup.
Bring to a boil, then reduce heat to remove scum and grease as it rises to the surface.
Add the shredded cabbage lettuces, sorrel, tarragon, chervil, and sugar.
Simmer until the vegetables are tender, taste for seasoning, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that gently fries the shredded vegetables and adds richness to the broth.
- Carrots
- Sweetness and color, and a firm texture that holds up during simmering.
- Leeks
- Mild onion-like aroma that builds flavor in the base.
- Cabbage lettuces
- Added near the end to soften in the stock while keeping a fresh, leafy texture.
- Turnips
- Firm, slightly peppery vegetable that adds body and bite to the soup.
- Onions
- Savory aroma and depth as they soften and brown lightly in the butter.
The step that matters
Frying the vegetables until lightly colored. Frying in butter over low heat browns the sugars and proteins gently, building savory flavor. Too much heat scorches the thin shreds and makes the broth bitter.
