Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Rump Steaks with Gravy
Ingredients
Directions
Prepare the meat
Simmer the meat gently for about 1.5 hours.
Strain off 1½ pints of the liquor for the sauce.
Make the gravy
Melt 2 ounces of butter in a stew-pan.
Stir in enough flour to make a stiff paste.
Add 1 tablespoon of claret or port wine, 1 tablespoon of mushroom ketchup, ½ teaspoon of salt, and ¼ teaspoon of ground black pepper.
Gradually add the strained liquor and let it boil for 15 minutes.
Skim the sauce and strain it again.
Serve
Serve the steaks with onions around the dish and pour the gravy over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the gravy and adds richness and a smooth mouthfeel to the sauce.
- Flour
- Forms a stiff paste with the butter that thickens the liquor into a gravy.
- Claret or port wine
- Adds acidity and depth of flavour to the sauce.
- Mushroom ketchup
- Adds savoury umami depth to the gravy.
- Liquor from simmered meat
- Provides the meaty liquid base that gives the gravy its body and flavour.
The step that matters
Adding the strained liquor to the flour paste. Flour thickens smoothly only when liquid is added gradually to the butter-flour paste while stirring. Adding it all at once can leave lumps, so the sauce should be stirred steadily as it boils.
