Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Make Mutton Broth Quickly
Ingredients
Directions
Prepare
Cut the meat into small pieces.
Place the pieces in a saucepan with bones, cold water, and no skin or fat.
Add the sweet herbs, onion, pepper, and salt.
Cover the saucepan.
Cook and finish
Bring the water to a boil quickly.
Remove the lid.
Continue boiling rapidly for 20 minutes, skimming the surface frequently.
Strain the broth into a basin.
If any fat remains on the surface, remove it by laying a piece of thin paper on top to absorb the grease.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meaty flavour and gelatin-rich body as it simmers in the water.
- Bones (in the method)
- Release collagen and minerals during simmering, giving the broth body and a richer mouthfeel.
- Cold water
- Acts as the cooking liquid that extracts flavour from the meat and bones.
- Onion
- Adds aromatic depth to the broth as it simmers.
The step that matters
Skimming the surface during the rapid boil. Rapid boiling churns fat and scum into the liquid, which can make the broth cloudy and greasy. Skimming removes these impurities so the broth stays clearer and cleaner-tasting.
Swap the onion
