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 ↓
To Warm Up Cold Rump-steaks
Ingredients
Directions
Prepare
Place the cold rump steaks in a stew pan.
Add the quartered onion, allspice, and black peppercorns.
Cover the steaks with boiling water and let them stew gently for one hour.
Make the gravy
In a bowl, mix the flour and butter together until smooth.
After an hour, add the flour and butter mixture to the stew pan.
Stir well over the heat for five minutes until thickened.
Serve
Serve the steaks and onions on a dish, pouring the gravy through a sieve over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steaks
- Provide the meat that becomes tender during long, gentle stewing.
- Flour
- Thickens the cooking liquid into a smooth gravy as it heats.
- Butter
- Blends with the flour and adds richness to the gravy.
- Onion
- Adds savory sweetness and aroma to the stewing liquid.
The step that matters
Stir the flour and butter into the gravy. Flour clumps if added raw to hot liquid without being blended smooth first. Stirring while it heats lets starch granules swell evenly, giving a smooth, thickened gravy.
Swap the allspice
How well each one fits the dish's main ingredients (onion, flour, butter):

Fit is the average pairing score against onion, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
