Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley meal
- Thickens the water into a jelly-like body as its starch gelatinizes on boiling.
- Red herrings
- Supply the main savory, fishy flavor and protein of the soup.
- Vinegar
- Adds a sharp acidity that brightens and balances the rich, earthy flavors.
The step that matters
Boiling the barley mixture to a thick consistency. Barley starch thickens only as it cooks and gelatinizes in boiling liquid. Stopping early leaves the soup thin, while overcooking can make it gluey and heavy. Watch the texture closely rather than the clock.
