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 ↓
Roast Beef
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
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 and season
Roast in the oven, basting frequently with its own drippings.
When partly done, season with coarse sea salt and black pepper.
Dredge the roast with sifted flour for a frothy appearance.
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 to keep warm.
Skim the fat from the drippings, then add 1 tablespoon of sifted flour, a little pepper, and 1 cup of boiling water.
Boil the mixture once and serve hot as gravy.

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
- Forms the main body of the dish, and its fat and connective tissue shape the meat's texture as it cooks.
- Butter or suet fat
- Coats the surface during basting, adding moisture and promoting browning.
- Sifted flour
- Dredged over the roast for a frothy surface, and thickens the drippings into gravy.
The step that matters
Roast for about 2 hours for a medium doneness, or 1.5 hours for rare.. Meat continues to cook after leaving the oven, and roast doneness depends on internal temperature rather than time alone. Overcooking dries the meat, so check it early.
“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.
