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 ↓

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 and roast
Preheat the oven to 400°F (200°C).
Wipe the roast thoroughly with a clean, wet towel.
Place the roast in a dripping pan and baste it well with butter or suet fat.
Roast in the oven, basting frequently with its own drippings.
When partly done, season with salt and pepper, then dredge with sifted flour.
Roast for about 2 hours for a medium doneness, or 1.5 hours for rare.
Make the gravy and serve
Remove the roast to a heated dish and keep warm.
Skim the fat from the drippings, add 1 tablespoon of sifted flour, a little pepper, and 1 cup of boiling water.
Boil once and serve hot in a gravy boat.

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
- Rib piece or loin roast
- Provides the meat that becomes tender and juicy during slow roasting.
- Butter or suet fat
- Fat for basting that carries heat over the surface and promotes browning.
- Sifted flour
- Dredged on the roast for a browned crust and thickens the drippings into gravy.
- Black pepper
- Adds sharp aroma and flavour to the seasoned crust and gravy.
The step that matters
Basting and roasting time. Basting with drippings keeps the surface moist and helps it brown evenly, while roasting time controls doneness. Roasting too long dries the meat and toughens it, so checking doneness matters.
“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.
