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
- Flour
- Thickens the stock into a smooth sauce as its starch swells when heated.
- Butter
- Adds fat and richness, and its browning contributes toasty flavor to the sauce.
- Stock
- Forms the liquid base of the sauce that the flour thickens.
- Mushrooms
- Add earthy flavor and body to the finished sauce.
The step that matters
Add the stock gradually while stirring constantly. Adding liquid slowly while stirring disperses the flour evenly, preventing lumps. Pouring it all at once can leave clumps of flour that stay hard to smooth out.
