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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the fat base of the roux and adds richness to the sauce.
- Flour
- Thickens the sauce when cooked with the butter into a roux.
- Cream
- Adds richness and body, giving the sauce a smooth, silky texture.
- Mushroom liquor
- Adds concentrated mushroom flavour to the liquid base of the sauce.
- Mushrooms
- Supply the main texture and earthy flavour of the sauce.
The step that matters
Add the mushrooms when the sauce begins to thicken. Adding mushrooms at the right point lets the sauce thicken properly before they are stirred in. Cooking the mushrooms only until heated through keeps them tender rather than rubbery, and keeps the sauce from thinning or scorching.
