Why it works: Flour and butter 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 ↓

Ingredients
Directions
Make the sauce
In a saucepan over medium heat, melt the butter.
Stir in the flour with a wooden spoon to form a smooth paste.
Gradually pour in the boiling water while stirring well.
Bring to a boil, season with pepper and salt, and serve.
Finish
For an acidic taste, add a few drops of vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to form the fat base that carries the sauce's flavour and richness.
- Flour
- Thickens the butter and water into a smooth sauce as it cooks.
- Boiling water
- Forms the liquid body of the sauce, thinned gradually into the flour paste.
- Vinegar
- Adds a sharp acidic note that brightens the rich butter flavour.
The step that matters
Stirring in the boiling water. Pouring the water in gradually while stirring well keeps the flour paste smooth. Adding it all at once can trap lumps of flour that are hard to whisk out.
