Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Breast of Lamb with Green Peas
Ingredients
Directions
Prepare
Remove the skin and excess fat from the lamb breast and cut it into neat pieces.
Melt the butter in a pan.
Cook
Fry the lamb pieces coated in flour, along with the onion, parsley, salt, and pepper.
Stew gently for 30 minutes, then skim off the fat.
Add the green peas and simmer until tender.
Serve
Arrange the meat on a serving dish and pour the gravy and peas over it.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb breast (in the method)
- Provides the main meat, which becomes tender through gentle stewing.
- Flour
- Coats the lamb and thickens the gravy as it cooks.
- Butter
- Adds fat for frying the lamb and onion, carrying flavour into the dish.
- Green peas
- Add sweetness and texture to the finished dish.
- Onion
- Adds savoury depth and aroma to the stewing liquid.
The step that matters
Skim off the fat after stewing. Lamb releases fat as it stews, and leaving it in makes the gravy greasy. Skimming after the gentle simmer lets the fat rise to the surface so it can be removed before the peas are added.
Swap the peas
How well each one fits the dish's main ingredients (flour, onion, pepper, butter, parsley):
- Black-eyed peafits better
- Chickpeafits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against flour, onion, pepper, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
