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
- Adds richness and carries flavor, and its milk solids help the roux brown.
- Flour
- Starch thickens the sauce once cooked in the butter to form a roux.
- Gravy
- Forms the liquid base that the roux thickens into a sauce.
- Champagne
- Adds acidity and aroma that brighten the rich sauce.
The step that matters
Slowly pour in the boiling gravy while stirring continuously. Flour starch must be dispersed evenly into the liquid. Adding the gravy gradually while stirring lets each starch granule separate and hydrate, which prevents lumps and gives a smooth, evenly thickened sauce.
“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.
