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 Mutton
Ingredients
Directions
Prepare
Trim off inedible parts of the mutton and wash it well.
Dry the meat with a clean cloth and place it in a roasting pan.
Add a little water to the pan for basting initially.
Roast
Roast for about 12 minutes per pound in a strong oven.
Do not salt the meat at first; salt it after it begins to roast well.
If browning too fast, cover with a sheet of white paper.
Baste often, and about 15 minutes before done, lightly dredge with flour and baste with butter.
Finish the gravy
Skim the gravy and thicken slightly with brown flour before serving.

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
- Mutton (in the method)
- Provides the meat that cooks through and browns in the roasting pan.
- Butter
- Adds fat that enriches the surface and helps it brown during basting.
- Flour
- Dredged over the meat and browned to form a crust, then thickens the gravy.
The step that matters
Salting timing. Salt added at the start can draw moisture out of the meat before it sets a crust. Waiting until the surface has begun to roast helps it brown well and keeps the juices in.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter):
- Raisinfits better
- Vanillafits better
- Coconutfits better
- Currantthe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
