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 ↓
Dutch Sauce
Ingredients
Directions
Make the sauce
In an earthenware pot or bain-marie, combine the butter, egg yolks, flour, and lemon juice or vinegar.
Gently heat the mixture, stirring constantly to prevent curdling. Do not allow the sauce to boil.
Serve
Add a few drops of vinegar just before serving if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and bind it into a smooth emulsion as they gently cook.
- Butter
- Provides fat for a rich, smooth texture and body in the sauce.
- Flour
- Helps stabilize the emulsion and adds body so the sauce holds together.
- Lemon juice
- Adds acidity that brightens the rich butter and egg flavour.
The step that matters
Gently heat the mixture without boiling. Egg yolks begin to set at moderate heat and can curdle or scramble if overheated. Constant stirring and avoiding boiling keep the sauce smooth and emulsified.
