Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Its starch thickens the liquid and gives the soup a chewy, filling body.
- Onion
- As it softens and cooks down, it adds aroma and a gentle sweetness.
- Turnip or carrot
- As it cooks soft, it adds body and a mild sweetness to the soup.
The step that matters
Keep the fire slow and steady. Barley starch and the vegetables' sugars can scorch on the bottom of the pot if the heat is too high over a long cook. A gentle, steady simmer over three hours or more keeps the soup from burning.
