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
The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Trim off inedible parts of the mutton and wash it well.
Dry the mutton with a clean cloth.
Roast
Place the mutton in a roasting pan and add a little water for basting.
Roast for about 12 minutes per pound in a strong oven at 400°F (200°C).
Do not salt at first; add salt after it begins to roast well.
Baste often.
Cover with white paper if it browns too quickly.
About 15 minutes before done, lightly dredge with flour.
Baste with butter.
Finish and serve
Skim the gravy.
Thicken slightly with brown flour.
Serve with currant jelly.

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 is roasted and carved, so its cooking time sets the whole method.
- Butter
- Adds richness and helps the surface brown and take on flavour during basting.
- Flour
- Dusted on near the end, it helps form a light browned crust on the meat.
- Currant jelly
- Its tartness cuts the richness of the roasted mutton and adds a sweet-sharp contrast.
The step that matters
Salt after the meat starts to roast. Salting at the start can draw out moisture before the surface has set, so the timing of salt is deliberately delayed until roasting is well under way.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter):

- 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.
