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 ↓
Spring Soup Without Meat
Ingredients
Directions
Prepare
Cut the cauliflower into small pieces and set aside the florets.
Chop the tender part of the cauliflower stalk into small pieces.
Prepare the rest of the vegetables and shred them finely.
Make the soup
Melt the butter in a large pot over medium heat.
Add the shredded vegetables and cauliflower stalk, cooking for 20 minutes without browning.
Pour in the water, add salt and pepper, and simmer gently until tender, about 1 hour.
Twenty minutes before serving, add the cauliflower florets.
Serve
Cut 2 or 3 slices of well-browned toast into small dice and place them in a serving bowl.
Adjust seasoning as needed and serve the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that softens the vegetables gently and adds richness to the soup.
- Cabbage
- Adds body and a mild, sweet vegetable flavour as it becomes tender.
- Leeks
- Add a mild onion-like sweetness that builds the base flavour of the soup.
- Cauliflower
- Provides tender pieces and mild flavour; florets are added late so they keep their texture.
The step that matters
Cooking the shredded vegetables in butter without browning. Gentle cooking softens the vegetables and draws out their sweetness. Browning would add bitter, roasted notes that change the clean flavour of the soup.
Swap the onion
How well each one fits the dish's main ingredients (lettuce, cabbage, carrot, turnip, leek, celery, cauliflower):
- Beetrootfits better
- Parsnipfits better
