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
Wash, trim, scrape, or peel the vegetables and cut them into very fine shreds or strips of even length.
Make the soup
In a stewpan, melt the butter over medium heat without letting it brown.
Dissolve the Marmite in hot water and add it to the vegetables.
Cook until the vegetables are tender, skimming off any scum that forms.
Season and serve
Season to taste with salt, pepper, and castor sugar. Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted gently without browning, it adds richness and a rounded flavour to the broth.
- Marmite
- Dissolved in the water, it adds savoury, salty depth to the soup.
- Cabbage lettuce
- Shredded leafy greens that soften during cooking and add body and mild flavour.
- Leek
- Adds a mild onion-like sweetness and aroma as it softens in the butter and water.
The step that matters
Melt the butter without browning. Browned butter takes on a nutty, bitter flavour that changes the soup's clean taste. Gentle heat keeps the butter's flavour mild and the vegetables tender rather than fried.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, leek, celery, cabbage, lettuce, butter):
