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 pieces in flour and place them in a stew pan with butter.
Braise
Brown the lamb pieces nicely, then cover with warm water.
Add parsley and onions, then simmer until the meat is cooked.
Skim off the fat, remove the onions and parsley, and finely mince the parsley.
Finish and serve
Return the minced parsley to the gravy along with the boiled asparagus tops.
Season with salt and pepper, simmer for a few more minutes, and serve.

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 slow simmering in liquid.
- Flour
- Coats the lamb so it browns well and helps thicken the gravy.
- Butter
- Adds fat for browning the lamb and enriches the flavour of the gravy.
- Parsley
- Adds fresh, green aroma to the gravy.
- Asparagus tops
- Add a tender, green vegetable element and fresh flavour to the finished gravy.
The step that matters
Browning the lamb pieces. Browning floured meat in butter creates a deep, savoury crust through the Maillard reaction. Pale, steamed pieces give a flat, grey-tasting gravy, so brown them in batches with space between pieces.
