Chef Tips from the Video
- Toast the barley briefly in a dry pan before adding it to the soup for a nuttier flavor.
- Use a mix of shiitake and button mushrooms for added umami.
- Finish with a drizzle of extra‑virgin olive oil for a silky mouthfeel.
Troubleshooting
Barley is still chewy after the cooking time.
Continue simmering for 5‑10 more minutes, adding a little extra stock or water if needed.
Soup is too thin.
Uncover the pot and simmer uncovered for 5‑10 minutes to reduce and thicken.
Soup is overly salty.
Add an extra cup of water or unsalted stock and simmer for a few minutes; adjust seasoning afterward.

Make-Ahead Tips
