Why it works: Parsley and pepper 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 Asparagus Tops
Ingredients
Directions
Prepare the lamb
Remove the skin and excess fat from the lamb and cut it into neat pieces.
Dredge the lamb pieces with flour and place them in a stew pan with butter.
Brown the lamb pieces nicely over medium heat.
Simmer and finish
Cover the meat with warm water and add parsley and onions.
Simmer until the meat is cooked through.
Skim off the fat and remove the onions and parsley.
Finely mince the parsley and return it to the gravy along with the asparagus tops.
Add salt and pepper, and simmer for a few more minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb breast
- Provides the meat that becomes tender through slow simmering in liquid.
- Flour
- Coats the lamb so it browns well and thickens the gravy.
- Butter
- Adds fat for browning the lamb and carries flavour into the gravy.
- Asparagus tops
- Add a fresh, green flavour and tender texture to the finished gravy.
- Button onions
- Release sweetness and aroma into the simmering liquid.
The step that matters
Brown the lamb pieces nicely. Browning creates deep flavour through the Maillard reaction. Pale lamb yields a weaker, less savoury gravy, so the pieces need space and steady medium heat to colour rather than steam.
Swap the onion
How well each one fits the dish's main ingredients (lamb, flour, butter, parsley, asparagus, pepper):

Fit is the average pairing score against lamb, flour, butter, parsley, asparagus, pepper. Candidates are from the same food group and used in at least 100 recipes.
