Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
A Good Vegetable Soup Maigre
Ingredients
Directions
Make the base
Melt the butter in a stewpan over low heat, shaking the pan gently.
Add the sliced onion, diced turnip, diced carrot, chopped celery, shredded spinach, and parsley.

Season with salt, pepper, Cayenne, and pounded mace.
Simmer gently for 15 minutes.
Before serving, stir in the white wine or mushroom ketchup.

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 carries flavour without browning them.
- Celery
- Adds savoury aroma and body to the vegetables as they cook down in the broth.
- Toasted bread
- Thickens the soup as it simmers and helps give it body once rubbed through a sieve.
- White wine or mushroom ketchup
- Adds acidity or savoury depth, stirred in at the end so its flavour stays bright.
The step that matters
Rubbing the mixture through a fine sieve. Pressing the cooked vegetables and bread through a fine sieve breaks them down into a smooth purée. Skipping or rushing this leaves the soup coarse and stringy.
Swap the onion
How well each one fits the dish's main ingredients (butter, turnip, carrot, celery, spinach, parsley, bread):
