Why it works: Butter and milk 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 ↓
Mushroom Soup
Ingredients
Directions
Prepare the base
Peel and boil the mushrooms for two hours.
In a separate bowl, mix the melted butter and flour until smooth.
Add the slightly heated milk and a small quantity of stock to the butter-flour mixture.
Finish the soup
Press the soft mushrooms through a fine colander.
Combine the mushroom puree with the milk mixture and season to taste.
Stir constantly in a double saucepan until well heated.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main flavour and body once pressed into a puree.
- Butter
- Adds richness and fat, carrying flavour through the soup.
- Flour
- Thickens the butter and milk mixture so the soup becomes smooth and creamy.
- Milk
- Forms the creamy liquid base that gives the soup its body.
The step that matters
Stir constantly in the double saucepan. Milk-based soups can scorch or form a skin on the bottom when overheated. A double saucepan gives gentle, indirect heat, and constant stirring keeps the flour-thickened mixture smooth and prevents sticking.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (mushroom, butter, flour, milk, pepper):
- Thymefits about as well
- Nutmegthe original
- Parsleyfits about as well
- Cinnamonfits about as well
Fit is the average pairing score against mushroom, butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
