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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Fried slowly until light brown, they add sweetness and savory depth to the soup.
- Butter
- Carries the frying of the vegetables and adds richness to the base.
- Flour
- Stirred into the fried vegetables, it thickens the soup slightly.
- Curry powder
- Provides the spiced, aromatic flavor that defines the soup.
- Knuckle of veal
- Simmered for hours, it releases gelatin and flavor into the broth, giving body.
- Boiled rice
- Added near the end, it adds starchy body and makes the soup more filling.
The step that matters
Skimming the broth well. Skimming removes foam and impurities that would cloud the broth and taste bitter. Removing fat after straining keeps the soup clean and light.
