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
- Melts and browns to add a nutty, toasted flavor and richness to the sauce.
- Browned flour
- Thickens the sauce as it cooks, giving it body and a toasted flavor.
- Vinegar
- Adds acidity that brightens the rich butter and flour base.
- Brown sugar
- Adds a little sweetness that balances the vinegar and cayenne.
The step that matters
Browning the butter without burning it. Butter solids darken quickly once the water has cooked off. Taking it just to a golden brown gives toasty flavor, while going further turns it bitter and dark.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (butter, flour, vinegar, sugar, pepper):
- Cinnamonfits better
- Tarragonfits better
- Nutmegfits better
- Celerythe original
Fit is the average pairing score against butter, flour, vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
