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

What each ingredient does

Pearl barley
Starch that thickens the water into a thick, smooth gruel as it boils.
Sugar
Adds sweetness to balance the mild, starchy flavour of the barley.
Sherry or port
Thins the finished gruel and adds a fortified wine aroma and sweetness.

The step that matters

Boiling until reduced by half. Barley starch keeps thickening as it cooks and water evaporates. Stopping too early leaves it thin, while overcooking makes it stiff and pasty, so check the texture as it reduces.

Swap the lemon

How well each one fits the dish's main ingredients (barley, cinnamon, sugar, sherry):

  4. Lemonthe original

Fit is the average pairing score against barley, cinnamon, sugar, sherry. Candidates are from the same food group and used in at least 100 recipes.
