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 the oven to 350°F (175°C).
Bone the shoulder of lamb and fill the cavity with a mixture of mushrooms, parsley, salt pork, cracker crumbs, sweet herbs, pepper, salt, and the raw egg.
Braise and serve
Braise the stuffed lamb shoulder in good stock or gravy.
Serve the lamb surrounded by cooked spinach and garnished with slices of egg.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb shoulder
- Main cut that becomes tender and moist during slow braising as its connective tissue softens.
- Mushrooms
- Add moisture and savory depth to the stuffing as they release juices during cooking.
- Salt pork
- Renders fat into the stuffing, adding richness and flavor to the lamb.
- Cracker crumbs
- Absorb juices and give the stuffing body so it holds together in the cavity.
- Raw egg
- Binds the stuffing as its proteins set when heated.
- Stock or gravy
- Braising liquid that keeps the lamb moist and adds savory flavor.
The step that matters
Braising the stuffed shoulder. The stuffing is enclosed in the meat, so heat must reach its center to set the raw egg and bind the mixture. Keeping the lamb submerged in liquid helps prevent it from drying out during the long, gentle cooking.
