Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and 41,516 recipes mention both. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Fresh Mushroom Soup
Ingredients
Directions
Prepare the mushrooms
Run some cold water over the mushrooms — do not let them stand in it.
Peel, cut off stems, and scrape them.
Cut in small pieces.
Make the soup
Add to the stock and boil fifteen minutes.
Make a roux of the butter and flour (do not let it brown).
Add this to the stock and mushrooms and stir until it thickens.
Season with the salt and pepper.
Serve
At serving time turn in the heated cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White stock
- Forms the liquid base that carries the mushroom flavour.
- Butter
- Carries flavour and fat, and forms the base of the roux.
- Flour
- Thickens the soup with the butter as a roux, giving it body.
- Cream
- Adds richness and a smooth, velvety texture at the end.
The step that matters
Make the roux without browning it. Flour cooked in butter thickens best while pale. Browning changes its colour and flavour and weakens its thickening power.
