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 ↓

Ingredients
Directions
Make the vegetable base
Cover vegetables with water, add seasoning and cook until well done.
Force through sieve.
Make the milk roux
Heat butter until light brown, stir in flour, and let mixture cook until it bubbles and is well blended.

Add to strained vegetables and let simmer until smooth and thickened.
Sprinkle with chopped parsley and serve with egg barley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during cooking to give the soup body and a thick, smooth texture.
- Butter
- Fat that is browned with flour to build a nutty flavour and make the thickening base.
- Flour
- Thickens the milk and butter mixture into a smooth roux that gives the soup body.
- Top milk
- Adds richness and creaminess and combines with the roux to thicken the soup.
- Onion
- Adds savoury sweetness and aroma as it cooks down into the vegetable base.
The step that matters
Gradually add hot milk to the flour mixture. Adding the milk slowly while stirring keeps lumps from forming in the roux. Simmering just below boiling then thickens the milk smoothly, and the mixture should not be allowed to boil hard.
Swap the onion
How well each one fits the dish's main ingredients (potato, celery, carrot, parsley, butter, flour, milk):
- Parsnipfits better
