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-steaks
Ingredients
Directions
Prepare the steaks
Heat 1 ounce of butter in a stew pan.
Add 2 onions and cook until softened.
Add the Rump‑Steaks and cook for 5 minutes on each side over low heat.
Cook the onions and steaks
Boil 1 pint of Button Onions for 30 to 60 minutes.
Add the cooking liquid from the onions to the steaks, adding broth or boiling water if needed to cover.
Season with 12 black peppercorns and salt, then simmer gently for 1.5 hours.
Strain off about 1.5 pints of the liquid for the sauce.
Make the sauce and serve
In a separate pan, melt 2 ounces of butter and 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 salt, and ¼ teaspoon of ground black pepper.
Gradually add the strained liquid, bring to a boil, skim, and strain again.
Serve the steaks with the 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
- Form the main meat that is cooked slowly in the stewing liquid until tender.
- Onions
- Soften and sweeten as they cook, adding flavour to the stock and gravy.
- Flour
- Thickens the melted butter into a paste that gives the strained liquid body as gravy.
- Butter
- Adds richness and carries flavour when browning the steaks and onions and thickening the sauce.
- Button onions
- Cook until tender and serve alongside the steaks as a mild, sweet accompaniment.
The step that matters
Simmer gently for 1.5 hours. Keeping the liquid at a gentle simmer rather than a hard boil lets the connective tissue in the rump steak break down slowly, producing tender meat without toughening or drying it.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, port wine, mushroom, ketchup, pepper):
