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 mutton 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.
Simmer and strain
Cover the saucepan and bring to a boil quickly.
Remove the lid.
Boil rapidly for 20 minutes, skimming frequently.
Strain the broth into a basin.
If any fat remains, remove it by placing a piece of thin paper on the surface; the fat will adhere to the paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat flavour and gelatine from its bones that give the broth body.
- Sweet herbs
- Add aromatic flavour that infuses into the broth as it cooks.
- Onion
- Adds savoury depth and aroma to the broth.
The step that matters
Skimming during the rapid boil. Impurities and fat rise to the surface as the broth boils. Skimming them off keeps the broth clear and clean-tasting rather than cloudy or greasy.
