Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Peas with Lamb
Ingredients
Directions
Cook the lamb and peas
Boil the lamb in enough water to cover it.
Add salt and onion.
When the lamb is half cooked, add the peas that have been boiled in another saucepan for 10 minutes.
Once the meat and peas are done, remove the fat.
Make the sauce
Thicken the broth with flour and add the pea water to create a butter sauce.
Flavor the sauce with parsley.
Finish and serve
Use the meat broth for soup.
Add one or two egg yolks and serve in cups.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Provides the main meat and rich flavor in the broth and sauce.
- Peas
- Add sweetness and body to the sauce as they break down.
- Flour
- Thickens the broth so it becomes a smooth, coating sauce.
- Onion
- Adds savory aroma to the cooking broth.
The step that matters
Thickening the broth with flour. Flour must be mixed in evenly before the liquid is hot enough to set, or it clumps into lumps. Stirring it into the broth as it cooks gives a smooth sauce that thickens as the starch swells.
Swap the peas
How well each one fits the dish's main ingredients (lamb, onion, flour, parsley):
- Chickpeafits better
- Lentilsfits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against lamb, onion, flour, parsley. Candidates are from the same food group and used in at least 100 recipes.
