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 ↓
Drawn Butter
Ingredients
Directions
Make the sauce
Rub the butter and flour together until well mixed.
Place the mixture in a double boiler with water and salt.
Cover and heat on the stove, shaking constantly until melted and just beginning to boil.
Do not allow it to boil, as this will make it oily and spoil the sauce.
Vary the sauce
For a variation, add chopped parsley and hard-boiled eggs to the drawn butter.
You can also add different herbs to create various sauces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the sauce base, providing richness and a smooth, buttery flavour.
- Flour
- Helps bind the butter and stabilise it so the sauce does not separate easily.
The step that matters
Do not let it boil. Boiling breaks the butter emulsion, separating the fat and making the sauce oily and spoiled. Gentle, constant shaking over moderate heat keeps it smooth.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (butter, flour, egg):
- Capersfits better
- Nutmegfits better
- Jalapenofits about as well
- Parsleythe original
Fit is the average pairing score against butter, flour, egg. 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.
