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
Stew the steaks
Place the cold rump steaks in a stewpan with the quartered onion, allspice, and black peppercorns.
Cover the steaks with boiling water and let them stew gently for one hour.
Make the gravy and serve
In a bowl, mix the flour and butter together until smooth.
After one hour, add the flour and butter mixture to the stewpan and stir well over the heat for five minutes.
Serve the steaks and onion on a dish, pouring the gravy over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steaks
- Slow stewing in liquid turns the tough meat tender and flavourful.
- Flour
- Thickens the cooking liquid into a smooth gravy as it heats.
- Butter
- Combines with the flour and adds richness and smooth body to the gravy.
The step that matters
Stirring the flour and butter into the stewpan. Adding the flour and butter mixture to hot liquid without stirring can leave lumps. Stirring well over heat for five minutes lets the starch swell and thicken the gravy evenly.
Swap the allspice
How well each one fits the dish's main ingredients (onion, flour, butter):
