What each ingredient does
- Barley
- Provides chewy texture and body as its starch softens and releases into the broth.
- Soup stock
- Forms the liquid base and carries most of the savory flavor.
- Butter
- Adds fat for richness and a smoother mouthfeel.
The step that matters
Cook the barley slowly in water for three hours. Barley is a dense grain that needs long, gentle simmering to hydrate and soften fully. Rushing it leaves the grains hard and chewy, while boiling too hard can break them apart and make the soup cloudy.
