Why it works: Parsley and onion 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 ↓
Braized Breast of Lamb
Ingredients
Directions
Prepare the lamb
Braise the whole breast of lamb until done.
Remove the small bones and flatten the breast between two dishes. Let it cool.
Cut the breast into small, brown chop-sized pieces.
Warm the pieces in the braising liquid.
Make the pea sauce
Prepare the peas with a little fresh butter. Drain the peas.
Simmer the peas over low heat with the ham, parsley, and green onions.
Once nearly done, remove the ham, parsley, and onions.
Finish the peas with the espagnole sauce and a little sugar.
Mix 1 teaspoon of flour with the peas.
Moisten the mixture with the braising liquid. Reduce the mixture.
Season with salt and pepper.
Assemble
Cover the meat with this mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb breast
- Provides the main meat, which becomes tender through long braising and is cut into pieces.
- Green peas
- Form the main vegetable body of the dish, adding sweetness and a soft texture.
- Fresh butter
- Adds richness and a silky mouthfeel to the peas.
- Espagnole sauce
- Adds body and savoury depth to the peas, thickening the mixture as it reduces.
The step that matters
Reduce the mixture after moistening it. Reducing concentrates the liquid and thickens it through evaporation, so the sauce coats the meat and peas rather than running off. Stop early and it will be thin; reduce too far and it becomes pasty or salty.
Swap the peas
How well each one fits the dish's main ingredients (lamb, butter, ham, parsley, onion, sauce, sugar):
- Beansfits better
- Chickpeafits better
- Sesamefits better
- Peasthe original
Fit is the average pairing score against lamb, butter, ham, parsley, onion, sauce, sugar. Candidates are from the same food group and used in at least 100 recipes.
