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
- Provides fat and rich flavour as the body of the sauce.
- Flour
- Thickens the melted butter and helps it hold together as a smooth sauce.
The step that matters
Heat until it begins to simmer. Once the mixture is hot enough to simmer, it should be removed from heat promptly, since overheating can cause the butter emulsion to separate and turn greasy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
