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 Saddle of Mutton
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.
Roast the mutton
Preheat the oven to 400°F (200°C).
Place the saddle of mutton in a roasting pan and pour boiling water over it.
Roast for 12 minutes per pound, basting often.
When it begins to brown, cover with white paper, lifting it to baste.
Ten minutes before serving, remove the paper, dredge the mutton with flour, baste with butter, and brown.
Make the gravy and serve
Skim the fat from the gravy, thicken with browned flour, season, and boil once.
Serve the gravy in a boat and pass currant jelly with the mutton.

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
- Saddle of mutton
- Is the main meat, cooked slowly so its fat renders and the meat stays moist.
- Butter
- Basting fat that helps the surface brown and take on color near the end.
- Flour
- Dredged onto the surface to help form a browned crust, and browned flour thickens the gravy.
- Currant jelly
- Adds sweetness and acidity that cut through the richness of the roasted meat.
The step that matters
Covering with white paper. Covering the meat once it starts to brown slows surface browning so the outside does not burn while the inside finishes cooking. Lifting it to baste keeps the surface moist.
Swap the currant

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