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 Shoulder of Lamb
Ingredients
Directions
Roast
Place the leg of lamb some distance from the fire.
Baste it frequently.
Shortly before done, move it nearer to the fire.
Dredge the lamb with flour and a little coarse sea salt.
Baste with melted butter for a frothy appearance.
Make the gravy
Empty the dripping pan.
Add hot water to the pan and stir well.
Pour the gravy over the meat through a fine sieve.
Serve
Serve with mint sauce and a salad.

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
- Leg of lamb
- Forms the main meat that is slowly roasted until tender and juicy.
- Flour
- Coats the surface, helping it brown and form a crust.
- Butter
- Adds fat and richness, and basting with it promotes browning and a glossy finish.
The step that matters
Shortly before done, move it nearer to the fire.. Moving the lamb closer only at the end lets the surface brown and crisp without overcooking the interior. Moving it too early risks a dry, burnt exterior before the centre is done.
Swap the mint
How well each one fits the dish's main ingredients (lamb, flour, butter, sauce):
- Capersfits better
- Jalapenofits better
- Parsleyfits better
- Mintthe original
Fit is the average pairing score against lamb, flour, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
