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 ↓
Steak and Mushrooms
Ingredients
Directions
Cook the steak
Broil the sirloin steak over a clear fire until cooked to your liking.
Season the steak with salt and pepper, then keep it hot on a dish.
Make the sauce
Open the can of mushrooms and cut each one in half.
In a saucepan, mix 2 tablespoons of butter with 1 tablespoon of flour until smooth.
Add ½ cup of boiling water.
Season with a little salt and pepper.
Heat the mushrooms in the saucepan until warmed through.
Pour the sauce around the steak.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin steak
- Is the main protein, cooked by direct high heat to brown the surface and set its texture.
- Butter
- Adds fat and richness to the sauce and helps carry flavour.
- Flour
- Thickens the butter and water into a smooth, lightly bodied sauce.
- Mushrooms
- Add savoury, earthy flavour and a soft texture to the sauce.
The step that matters
Mixing the butter and flour until smooth. Flour must be fully blended with the melted butter before the water goes in. Lumps that are not dispersed will not hydrate evenly, leaving a grainy or pasty sauce.
