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
Combine butter, vinegar, water, and egg yolks in a small saucepan.
Stir over low heat until the sauce thickens, about 10 minutes. Do not let it boil, or the sauce will curdle.
Add lemon juice and flour to achieve desired consistency.

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
- Egg yolks
- Thicken the sauce as they set with gentle heat, giving it body and richness.
- Butter
- Adds fat for a smooth, rich mouthfeel and glossy texture.
- Lemon juice
- Adds acidity that brightens the sauce and balances its richness.
- Flour
- Adds starch that helps thicken the sauce to the desired consistency.
The step that matters
Keep the heat low and do not boil. Egg yolks thicken through gentle heat, but boiling causes them to scramble and curdle, so the sauce must be stirred over low heat and never allowed to boil.
