Why it works: Mushroom and butter 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 ↓
Mushroom Pie
Ingredients
Directions
Prepare the filling
Chop the mushrooms into small pieces and season with salt and pepper.
In a bowl, combine the chopped steak and minced onion, then season.
If the steak is lean, add a small piece of suet or butter.
Stew the filling
Place the chopped steak and mushrooms in a deep saucepan, cover, and stew slowly until tender.
Assemble and bake
Prepare a pie crust as for beefsteak pie, lightly browning the bottom crust in a deep dish.
Add the mushroom and steak stew to the crust and cover with a top crust, lightly punctured.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Common mushrooms
- Release moisture and savory flavor into the filling as they stew.
- Round steak
- Provides the meaty body of the filling, which becomes tender through slow stewing.
- Suet or butter
- Adds fat and richness to a lean steak, keeping the filling moist.
- Onion
- Adds aromatic sweetness and depth to the meat filling.
The step that matters
Stew slowly until tender. Round steak is a lean, tough cut. Slow, covered stewing breaks down its connective tissue gradually, so the meat becomes tender rather than dry or chewy.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, butter, pepper):

- Onionthe original
Fit is the average pairing score against mushroom, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
