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
In a saucepan, melt 2 ounces of butter over medium heat until it bubbles.
Sprinkle in the flour and stir with a whisk until the flour is cooked but not browned.
Gradually mix in the water or stock until well combined.
Remove from heat and strain through a sieve.
Stir in the remaining 1 ounce of butter until melted and mixed.
For a slightly acidic flavor, add vinegar or lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Gives the sauce its rich flavor and smooth, glossy mouthfeel as it melts into the liquid.
- Flour
- Thickens the butter and liquid into a smooth sauce as its starch swells when heated.
- Water or white stock
- Forms the liquid base that the cooked flour thickens into a pourable sauce.
The step that matters
Cooking the flour. Stirring the flour in the hot butter cooks out its raw starch taste and lets it thicken evenly. Cooking it until browned changes the flavor and colour, and adding liquid too fast can cause lumps.
