Why it works: Butter and flour 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
Wash the mutton well and dry it with a clean cloth.
Preheat the oven to 400 °F (200 °C).
Place the mutton in a roasting pan with a little water.
Pour 1 cup of boiling water over the meat when you first put it in the oven.
Roast and baste
Roast the mutton for about 12 minutes per pound.
Baste the mutton often with salt and water.
Baste the mutton with the gravy.
If the mutton browns too quickly, cover it with a large sheet of white paper.
Finish and serve
Skim the gravy.
Thicken the gravy slightly with browned flour.
Serve the mutton with currant jelly.

Butter and flour 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 by dry roasting so its surface browns and its interior cooks through.
- Browned flour
- Thickens the pan gravy and adds a toasted, nutty flavour.
- Butter
- Adds fat for basting, helping the surface brown and stay moist.
- Currant jelly
- Adds sweet-tart acidity that balances the rich flavour of the mutton.
The step that matters
Covering the mutton if it browns too quickly. Sugars and proteins on the surface brown fast at high heat and can scorch before the interior cooks. A loose covering of white paper slows surface colour while the meat finishes cooking through.
Swap the currant

Fit is the average pairing score against mutton, butter, flour. 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.
