Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 12,525 recipes mention both. Both carry trans-2-decenal, which smells waxy, orange. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Main ingredient that softens when stewed and gives the dish its flavour.
- Cream or new milk
- Provides richness and the base of the white sauce.
- Flour
- Thickens the liquid into a smooth sauce as it cooks.
- Butter
- Fat that blends with the flour to form a roux, adding richness to the sauce.
The step that matters
Thicken the sauce with flour blended in melted butter. Flour must be blended smoothly into the melted butter before the liquid is added, so it cooks into a roux. Adding it lumpy or raw leaves a pasty taste and uneven, grainy thickness.
