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 ↓
Roast Shoulder of Lamb
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 350°F (175°C).
Stuff and braise
Bone the shoulder of lamb and fill the cavity with a stuffing made from mushrooms, parsley, salt pork, cracker crumbs, herbs, pepper, salt, and the raw egg.
Braise the stuffed lamb in a roasting pan with the stock or gravy.
Serve
Once cooked, serve the lamb surrounded by spinach and garnished with slices of egg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb shoulder
- Provides the main meat, which becomes tender and juicy through slow braising.
- Raw egg
- Binds the stuffing so it holds together when sliced and served.
- Cracker crumbs
- Absorb juices and give the stuffing body and a soft texture.
- Salt pork
- Adds fat and savoury richness that keeps the stuffing moist.
- Mushrooms
- Add moisture and earthy flavour to the stuffing.
The step that matters
Braise the stuffed lamb in a roasting pan with the stock or gravy. Braising in liquid breaks down the connective tissue in the shoulder slowly, making the meat tender. Cooking it too hot or too briefly can leave it tough, and the stuffing may not cook through in the centre.
