Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Easy Mushroom Soup
Ingredients
Directions
Prepare the mushrooms
Peel and wash the mushrooms.
Simmer the mushrooms in a little water for 10 minutes.
Remove the mushrooms and chop them finely, reserving the water as stock.
Make the soup
Prepare the milk as you would for any cream soup, adding a little flour to thicken it.
Stir in plenty of butter, salt, and a little cayenne pepper.
Add the chopped mushrooms and reserved stock to the milk, and serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main flavor and body of the soup once chopped and added.
- Milk
- Forms the creamy base of the soup.
- Flour
- Thickens the milk so the soup becomes creamy rather than watery.
- Butter
- Adds richness and a smooth, rounded mouthfeel.
The step that matters
Thickening the milk with flour. Flour must be mixed in so it hydrates and its starch swells evenly in the warm milk; if it is added in lumps or not cooked enough, the soup stays grainy or tastes raw and floury.
