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
Bring the water to a rolling boil in a large pot.
Add all the vegetables except the potatoes and tomatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Adds bulk and a mild sweetness as it softens in the broth.
- Potato
- Thickens the broth slightly as its starch releases during simmering.
- Carrot
- Adds sweetness and color, and holds its texture through long simmering.
- Tomatoes
- Contribute acidity and body, giving the broth depth of flavor.
- Butter or drippings
- Adds fat and richness, carrying flavor through the broth.
The step that matters
Adding the potatoes and tomatoes after the first hour. Potatoes and tomatoes added at the start would break down into mush during the two-hour simmer. Holding them back keeps their texture intact.
Swap the tomato
How well each one fits the dish's main ingredients (cabbage, potato, carrot, turnip, onion, leek, celery):
- Parsnipfits better
- Beetrootfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against cabbage, potato, carrot, turnip, onion, leek, celery. Candidates are from the same food group and used in at least 100 recipes.
