Why it works: Turnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Vegetable Soup
Ingredients
Directions
Prepare the vegetables
Wash, peel, and cut the vegetables into very thin shreds.
Make the soup
Melt the butter in a large pot over medium heat.
Add the vegetables and stir for 10 minutes without browning them.
Dissolve the MARMITE in the water and add it to the pot.
Let the mixture simmer for about an hour, skimming off any scum.
Season with salt, pepper, and nutmeg.
Thicken and serve
Mix the flour with the milk to form a smooth paste.
Add the paste to the soup and boil for another 10 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and carries flavour while the vegetables soften gently in the pot.
- Flour
- Mixed with milk, it thickens the broth to a smooth, lightly body-rich texture.
- Milk
- Combined with flour, it adds creaminess and helps thicken the soup.
- Potatoes
- Starchy vegetable that softens during simmering and helps give the soup body.
- Turnip
- Firm root vegetable that becomes tender in the simmering broth, adding earthy flavour.
The step that matters
Stir the vegetables without browning them. Browning adds roasted, bitter notes that change the soup's clean, mild flavour. Gentle stirring over medium heat softens the vegetables while keeping them pale.
