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 ↓
Mutton and 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).
Roast
Place the leg of mutton in the oven and baste it immediately with butter.
Sprinkle a little coarse sea salt on the meat.
When the meat is nearly done, dredge it with flour.
Roast for 1 hour and 15 minutes for a 6-pound leg.
For a 12-pound leg, roast for 2 hours.
Serve
Serve with good plain gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Is the main cut of meat, providing the substance and flavour of the dish.
- Butter
- Bastes the surface, adding moisture and richness while the meat roasts.
- Flour
- Dredged over the meat near the end, helping form a light crust that browns.
The step that matters
Dredging with flour near the end. Flour added too early can scorch or burn in the hot oven before the meat is cooked. Adding it when the meat is nearly done lets it form a browned, crisp coating.
Swap the clove
How well each one fits the dish's main ingredients (mutton, flour, butter):
- Capersfits better
- Turmericfits better
- Nutmegfits better
- Clovethe original
Fit is the average pairing score against mutton, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
