What each ingredient does

Pearl barley
Its starch thickens the liquid as it simmers and releases flavour into the water.

The step that matters

Boil until the mixture reduces to half. Reducing by half concentrates the liquid and the dissolved barley starch, so the final thickness depends on how far it is cooked. Stopping too early leaves it thin, and boiling too long makes it dense.
