Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Brown Sauce
Ingredients
Directions
Heat the cream in a saucepan until boiling.
In a bowl, mix the flour with a little cold milk to form a smooth paste.
Add the flour mixture to the boiling cream and stir constantly until thickened.
Reduce heat and cook in a double boiler for 5 to 10 minutes.
Optionally, flavor the milk with onion before adding the flour.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Thin cream
- Provides the liquid base and richness that the sauce is built on.
- Flour
- Thickens the sauce as its starch swells and gelatinizes when heated in the liquid.
The step that matters
Adding the flour paste to the boiling cream. Flour starch clumps if it hits hot liquid unevenly. Stirring constantly disperses the paste so the starch hydrates and thickens evenly into a smooth sauce.
