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

- Thymefits better
