Why it works: Flour and butter 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 ↓
Roast 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).
Place the lamb in a dripping pan and dash with boiling water.
Roast
Cook for 15 minutes per pound, basting often.
Ten minutes before removing, dredge the lamb with flour and baste with butter.
Finish
Pour off excess fat, then make gravy in the pan and mix in currant jelly.

Flour and butter 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
- Lamb
- The main cut, which is roasted slowly and stays moist when basted during cooking.
- Flour
- Dusted on the surface, it helps form a browned crust and later thickens the pan gravy.
- Butter
- Adds fat for basting, which promotes browning and a richer flavor on the surface.
The step that matters
Cook for 15 minutes per pound, basting often.. Cooking time depends on the weight of the lamb, and meat keeps cooking after it leaves the oven, so timing by weight and basting to keep the surface moist both matter for a juicy result.
