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
Ingredients
Directions
Melt half the butter in a saucepan over low heat, being careful not to let it brown.
Add the flour and mix well.
Gradually add the hot water, stirring rapidly as it thickens.
Once smooth, add the remaining butter in small pieces and stir until absorbed.
Season with salt and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat, giving it rich flavour and a smooth, glossy mouthfeel.
- Flour
- Thickens the liquid as its starch swells with heat, giving the sauce body.
- White stock or hot water
- Forms the liquid base that the flour thickens into a pourable sauce.
The step that matters
Gradually add the hot water while stirring rapidly. Adding liquid slowly while stirring keeps the flour dispersed, preventing lumps. Starch thickens as it heats, so the sauce must be stirred to keep it smooth.
