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
Ingredients
Directions
Prepare the steaks
Preheat your grill or broiler.
Season the rump steaks with coarse sea salt and black pepper.
Broil the steaks, turning frequently with steak tongs.
Once cooked, place the steaks on a hot dish and rub butter on each steak.
Make the sauces and garnish
Warm catsup in the dish before serving.
Chop eschalots finely and warm them in the dish with or without catsup.
Slice onions and cook them in a pan with a little butter and 2 tablespoons of water until browned.
Add ½ cup of gravy or broth to the onions and simmer until tender.
Strain and chop the onions, then return them to the gravy.
Season with salt, pepper, mushroom catsup, and port wine, and simmer for 5 minutes.
Pour the onion gravy onto the dish and place the broiled steak on top.
Rub more butter on the steak.
Chop an anchovy and mix it with ¼ cup of melted butter and pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steaks
- Provide the main meat, which is cooked by broiling to brown the surface and stay tender inside.
- Butter
- Adds richness and moisture when rubbed onto the hot steak and cooked onions.
- Onions
- Add sweetness and savory depth when browned and simmered into the gravy.
The step that matters
Turning the steaks while broiling. Frequent turning with tongs helps the steak cook evenly and brown without drying out, since the surface heats much faster than the centre.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (pepper, butter, mushroom, port wine, anchovy):
- Capsicumfits better
- Shallotfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against pepper, butter, mushroom, port wine, anchovy. Candidates are from the same food group and used in at least 100 recipes.
