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

What each ingredient does

Carrots
Add sweetness and aromatic flavour as they soften during simmering.
Onions
Build savoury depth and sweetness as they cook down in the liquid.
Butter
Carries fat-soluble aromatics and helps the vegetables brown lightly when fried.
Wine or cider
Provides acidity and liquid that draws flavour from the vegetables and herbs.
Peppercorns
Release pungent aroma and warm spice into the simmering liquid.
Allspice berries
Contribute warm, clove-like aroma to the marinade.

The step that matters

Simmer for 1.5 hours, then strain. A long, gentle simmer extracts flavour from the vegetables and spices, while a full boil can make the liquid cloudy and bitter. Straining removes solids so the liquid is clear and smooth for use.

Swap the clove
