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 ↓
Stewed Rump-steaes
Ingredients
Directions
Prepare
Ensure the rump steaks are thicker than for broiling and of uniform thickness.
Melt 1 ounce of butter in a stew-pan and add 2 onions.
Add the rump steaks and cook over low heat for 5 minutes, then turn and cook for another 5 minutes.
Stew
Boil 1 pint of button onions for 30 to 60 minutes.
Add the cooking liquid from the button onions to the rump steaks.
If needed, add broth or boiling water to cover.
Add 12 corns of black pepper and ¼ teaspoon coarse sea salt, then simmer gently for 1.5 hours.
Strain off about 1½ pints of the liquid for the sauce.
Make the sauce
In a separate pan, melt 2 ounces of butter, then stir in enough flour to make a stiff paste.
Optionally, add 1 tablespoon of claret or port wine, 1 tablespoon of mushroom ketchup, ½ teaspoon of coarse sea salt, and ¼ teaspoon of ground black pepper.
Gradually add the strained liquid, bring to a boil for 15 minutes, skim, and strain again.
Serve
Serve the rump steaks with the button 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
- Rump steaks
- Thick, uniform cuts stay tender and juicy through long, gentle stewing.
- Butter
- Adds richness and carries flavour when it is melted and cooked into the flour paste.
- Flour
- Forms a paste with the butter that thickens the strained liquid into a gravy.
- Onions
- Soften and sweeten as they cook, adding savoury depth to the stewing liquid.
- Button onions
- Become tender and mild, serving as a side that absorbs flavour from the dish.
The step that matters
Gentle simmering of the steaks. Rump is a tough cut. Keeping the liquid at a gentle simmer breaks down connective tissue slowly, while a hard boil toughens and dries the meat.
Swap the onion
How well each one fits the dish's main ingredients (butter, corn, pepper, sauce, flour, port wine, mushroom):
- Capsicumfits better
