Why it works: Flour and capers match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,024 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Drawn Butter
Ingredients
Directions
Make the sauce
Beat the butter and flour together until creamy.
Stir in the boiling water.
Place the mixture in a dish over boiling water and let it melt.
Heat until it begins to simmer, but do not simmer directly on coals.
Finish and serve
If using with fish, add chopped eggs and nasturtiums or capers.
If using with boiled fowl, add oysters while simmering and heat through.

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
- Forms the rich base of the sauce and carries its flavor and smooth mouthfeel.
- Flour
- Thickens the melted butter so the sauce becomes smooth rather than greasy.
- Boiling water
- Thins the butter and flour paste into a pourable sauce.
The step that matters
Heat until it begins to simmer, but do not simmer directly on coals. Direct heat from coals can scorch the butter and cause it to separate or taste burnt. Gentle indirect heat keeps the emulsion smooth and the flavor clean.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (butter, flour, egg, oyster):
- Capersthe original
- Nutmegfits about as well
- Parsleyfits less well
- Jalapenofits less well
Fit is the average pairing score against butter, flour, egg, oyster. Candidates are from the same food group and used in at least 100 recipes.
“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.
