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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the broth into a smooth sauce that clings to the beef.
- Butter
- Adds richness and helps the flour blend into the broth.
- Cold roast beef
- Provides the main protein, which warms through in the sauce.
- Good broth
- Forms the liquid base of the sauce and carries its flavor.
- Ketchup
- Adds sweetness and acidity to season the sauce.
The step that matters
Stir in the sliced beef and heat through. Heating the thin, already-cooked beef gently in the thickened sauce keeps it tender. Boiling it hard can toughen the meat and cause the sauce to break or become grainy.
