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 ↓
Canned Mushrooms Sauce
Ingredients
Directions
Combine the juice from the canned mushrooms with boiling water or broth in a saucepan and bring to a boil.
In a small bowl, mix the butter and flour to form a paste. Stir the paste into the boiling mixture to thicken.
Squeeze in the juice of half a lemon and add the mushrooms. Boil for about five minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter and flour
- Form a paste that thickens the liquid into a smooth sauce as it heats.
- Mushroom juice
- Provides the main savoury, mushroom-flavoured liquid base for the sauce.
- Lemon juice
- Adds acidity that brightens the flavour of the rich sauce.
The step that matters
Stir the flour paste into the boiling liquid. Flour thickens sauces only when it is dispersed and heated. Adding it as a paste and stirring it into boiling liquid helps prevent lumps and lets the starch swell evenly into a smooth sauce.
Swap the lemon
How well each one fits the dish's main ingredients (mushroom, butter, flour):

- Lemonthe original
Fit is the average pairing score against mushroom, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
