Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley meal
- Starch thickens as it cooks in the water, giving the soup its jelly-like body.
- Red herrings
- Pounded fish meat adds savory, rich flavor and body to the soup.
- Vinegar
- Adds acidity that brightens the flavor and balances the savory richness.
The step that matters
Boil until thick. Barley starch swells and thickens as it heats in water. Stop too early and the soup stays thin; cook too long without stirring and it can stick and scorch on the pot base.
