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 the meat
Trim any inedible parts from the meat, then wash and dry it with a clean cloth.
Place the meat in a roasting pan and add a little water for initial basting.
Roast
Roast for about 12 minutes per pound in a strong fire.
Do not salt the meat initially to prevent it from hardening.
Salt it after it begins to roast well.
If the meat browns too quickly, cover it with a sheet of white paper.
Baste the meat often.
About 15 minutes before it's done, lightly dredge it with flour and baste with butter.
Finish and serve
Skim the gravy and thicken it slightly with brown flour.
Serve with currant jelly or another tart sauce.

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 main meat, which turns tender and browns as it roasts.
- Butter
- Basting fat that adds richness and helps the surface brown and gain flavour.
- Flour
- Dredged over the meat and browned, it helps form a crisp, golden crust.
- Currant jelly
- Tart sauce that balances the richness of the roasted meat.
The step that matters
Salting after the meat begins to roast. Salt applied too early can draw out moisture and slow browning, so salting once the surface is roasting helps the meat brown well and keeps it juicy.
Swap the currant

Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
