Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Shoulder of Lamb
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 400°F (200°C).
Season the shoulder of lamb with flour and salt.
Roast and serve
Roast the lamb for twenty minutes, basting it with butter occasionally.
Remove from the oven and let it rest before serving.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Shoulder of lamb
- The main cut; slow roasting softens its connective tissue, leaving the meat tender.
- Butter
- Adds fat and richness, and its milk solids help the surface brown during basting.
- Flour
- Coats the lamb so the surface dries and browns into a crisp, flavourful crust.
The step that matters
Let the lamb rest before serving. Heat pushes juices toward the centre of the meat. Resting lets them redistribute, so the slices stay moist rather than running out onto the board when cut.
