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
Wash the roast well and dry it with a clean cloth.
Roast
Place the roast in a dripping pan and add a little water to baste it initially.
If the fire is very hot, roast for 12 minutes per pound.
If it browns too quickly, cover it with a sheet of white paper.
Baste often, and 15 minutes before it's done, dredge the meat lightly with flour and baste with butter.
Serve
Garnish the dish with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton roast
- Provides the main meat, which becomes tender and juicy as it roasts.
- Flour
- Dredged over the meat near the end, it helps form a light browned crust.
- Butter
- Brushed on during basting, it adds fat for richer flavour and browning.
The step that matters
Covering the roast if it browns too quickly. Over high heat the surface can darken before the interior cooks through. A sheet of white paper shields the outside from direct heat, slowing browning while the centre finishes cooking.
Swap the parsley
How well each one fits the dish's main ingredients (mutton, flour, butter):
- Capersfits better
- Turmericfits about as well
- Nutmegfits about as well
- Parsleythe original
Fit is the average pairing score against mutton, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
