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 ↓

Prepare the mushrooms

Soak the mushrooms in cold, slightly salted water, then drain and dry them.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Button mushrooms: Provide the main body and earthy flavour of the sauce.
Béchamel or white sauce: Forms the creamy base that carries the mushrooms.
Flour: Thickens the sauce through starch gelatinisation as it cooks.
Butter: Adds richness and a smooth, rounded mouthfeel.

The step that matters

Simmer until the mushrooms are tender. Mushrooms hold a lot of water and can stay rubbery if undercooked. Simmering gently softens their cell walls and releases flavour into the sauce, while a hard boil can make the sauce break or scorch on the base of the pan.
