Why it works: Barley and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 128 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Provides the body and starchy texture that thickens and gives the soup its substance.
- Flour
- Cooked in butter, it forms a roux that helps thicken the soup.
- Milk
- Adds richness and a creamy body to the soup.
- Corn starch
- Added dissolved in cold water, it thickens the stock when briefly boiled.
- Chicken or veal stock
- Forms the savoury liquid base that carries the flavour of the soup.
The step that matters
Add the corn starch dissolved in cold water. Starch must be dissolved in cold liquid first so it does not clump, then briefly boiled so it swells and thickens the soup evenly.
