Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Pearl barley
Its starch thickens the liquid as it simmers, giving the gruel body.
Port wine
Adds fruity sweetness and acidity, and a deeper aroma to the gruel.
Sugar
Adds sweetness that balances the port and the spice.

The step that matters

Simmer gently until the liquid is reduced by half. A gentle simmer lets the barley release its starch slowly and evenly. Boiling hard can make the barley break apart unevenly and scorch on the bottom of the pan.
