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 or Sauce for Fish
Ingredients
Directions
Make the sauce
Mix butter, flour, salt, hard-boiled egg, and half cup of boiling water or milk into a smooth cream.
Add hot water to the sauce, cook over a saucepan until it thickens smoothly.
Serve
Pour the sauce over chopped fish, stir together, and add small bits of parsley.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, velvety mouthfeel to the sauce.
- Flour
- Thickens the sauce as it cooks, giving it body.
- Hard-boiled egg
- Adds body and a rich, creamy texture to the sauce.
The step that matters
Cooking the sauce until it thickens smoothly. Flour must be fully cooked in hot liquid to swell and thicken evenly. Heating too quickly or unevenly can cause lumps or a pasty taste, so keep the heat moderate and stir steadily.
Swap the parsley
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.
