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 ↓
Lamb or Mutton Roasted
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 the roast
Preheat the oven to 400°F (200°C).
Place the roast in a dripping pan and rub it all over with flour.
Dot the top with bits of butter and add a lump in the pan.
Add a little boiling water and salt the roast.
Roast
Roast for 30 minutes or until it begins to brown.
Baste frequently.
Turn the roast halfway through cooking if not covered.
Cook for 15 to 20 minutes per pound, keeping enough water in the pan for basting.
Serve
Once done, transfer to a hot platter.
Make the gravy thick enough to serve. Add water or flour as needed. Stir to prevent burning.

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
- Lamb
- Forms the meat that is roasted, and its fat and juices flavour the dish.
- Flour
- Rubbed on the surface, it helps the outside brown and thickens the gravy.
- Butter
- Dotted over the top, it adds fat that promotes browning and richness.
- Boiling water
- Added to the pan, it keeps moisture for basting and forms the base of the gravy.
The step that matters
Keep enough water in the pan for basting. Without liquid in the pan the drippings can scorch and the surface dries out. Basting moistens the meat and promotes even browning while it roasts.
“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.
