Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Lamb Broth
Ingredients
Directions
Prepare
Cover the lamb pieces with cold water and let them stand for 30 minutes.
Place the pot on the stove and heat gradually.
Add salt, peppercorns, and the onion when heating.
Simmer and strain
Once it begins to boil, cook slowly for 30 minutes.
Do not skim until the broth is strained.
Strain the broth and season to taste.
Skim off all the fat before serving.
Add a little well-cooked rice if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean lamb meat
- Provides the main flavour and body of the broth as it simmers.
- Onion
- Adds aromatic sweetness to the broth as it cooks.
The step that matters
Skim off all the fat before serving. Fat that is not removed sits on the surface and makes the broth greasy. Skimming only after straining keeps the fat from being removed too early, while the broth is still cooking and clouding.
Swap the onion
How well each one fits the dish's main ingredients (lamb, meat, rice):

Fit is the average pairing score against lamb, meat, rice. Candidates are from the same food group and used in at least 100 recipes.
