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 ↓
Cream of Mushrooms
Ingredients
Directions
Prepare the mushrooms
Wash and peel the mushrooms, discarding the stems, and chop them finely.
In a saucepan, combine the chopped mushrooms and water, cover, and cook for 20 minutes.
Make the cream sauce
In a separate bowl, blend the butter and flour until smooth.
Gradually add the cream to the butter and flour mixture, stirring until smooth.
Add the cooked mushrooms and their liquid to the cream mixture, stirring well.
Season and serve
Season with salt and pepper, and serve with a tablespoon of whipped cream in each dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh mushrooms
- Provide the main flavour and bulk of the soup, releasing liquid as they cook.
- Butter
- Adds richness and fat, and forms the base for the flour-thickened sauce.
- All-purpose flour
- Thickens the cream by swelling with the butter and liquid to give a smooth body.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
The step that matters
Blending the butter and flour, then adding the cream gradually. Flour clumps if it meets liquid too quickly. Blending it with butter first and adding cream slowly, while stirring, lets the starch disperse evenly so the sauce thickens smoothly without lumps.
