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 roux
In a saucepan, melt half the butter without browning it.
Add the dry flour and mix well.
Thicken and finish
Gradually add the hot water while stirring rapidly until thickened.
Once smooth, add the remaining butter in small pieces and stir until absorbed.
Finally, add salt and pepper.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Adds rich flavor and smooth mouthfeel, and its fat carries the sauce's taste.
- Flour
- Starch thickens the hot liquid as its granules swell and gelatinize.
- Hot water or white stock
- Forms the sauce's liquid base that the flour thickens.
The step that matters
Adding the hot liquid gradually while stirring. Flour granules must be dispersed before the starch swells in heat. Pouring the liquid in slowly and stirring rapidly keeps the flour evenly mixed, so the sauce thickens smooth instead of forming lumps.
