Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Drawn-butter Sauce
Ingredients
Directions
Make the sauce
In a saucepan, melt half the butter over medium heat until it bubbles.
Sprinkle in the flour and stir well for 2 minutes.
Remove from heat and gradually add the boiling water, stirring constantly until thick and smooth.
Bring the sauce to a boil while stirring constantly.
Return to low heat and add the remaining butter, cut into pieces, along with the salt and pepper.
Finish and serve
If the sauce is not completely smooth, strain it before serving.
For a slightly acidic flavor, add a few drops of vinegar or lemon juice just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and rich flavor, and forms the base of the sauce.
- Flour
- Thickens the sauce as it cooks with the water, giving it body.
- Boiling water
- Forms the liquid of the sauce, which the flour thickens into a smooth consistency.
The step that matters
Adding the boiling water to the roux. Adding the liquid gradually while stirring constantly keeps the flour evenly dispersed, preventing lumps and giving a smooth, thick sauce.
