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
- Carrots
- Break down into a smooth puree that gives the soup its body and sweet flavour.
- Rice
- Softens in the milk and releases starch, adding body and thickness to the soup.
- Flour
- Thickens the soup when cooked with butter and liquid, giving it a smoother, heavier texture.
- Butter
- Adds richness and fat, carrying flavour and giving a smooth mouthfeel.
- Milk
- Provides creaminess and a mild, rounded flavour as the main liquid with the rice.
- Onion
- Cooked slowly in butter to build a savoury aroma as the soup's base flavour.
The step that matters
Bring the soup to a boil. Milk-based soups thickened with flour can scorch on the bottom or separate if boiled too hard or left unstirred. Stir often and keep the heat controlled once it reaches a boil.
