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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while the flour is cooked into it.
- Flour
- Thickens the liquid into a smooth white sauce as it cooks with the butter.
- Salsifis
- Forms the main vegetable, cooking gently until tender in the sauce.
The step that matters
Dissolve the flour in the melted butter, stirring well. Stirring keeps the flour evenly distributed so it does not form lumps. Cooking the flour briefly in the fat before adding liquid gives a smooth sauce that thickens evenly.
