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 ↓
Sauce Allemande
Ingredients
Directions
Make the sauce base
Melt the butter in a saucepan over low heat.
Mix in the flour until well combined.
Gradually add the consomme, salt, and pepper, stirring until boiling.
Boil for 15 minutes, then remove from heat.
Finish with egg yolks
Once the sauce stops boiling, mix the egg yolks with a little water.
Quickly stir the egg mixture into the sauce using an egg beater to make it light.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
- Flour
- Thickens the sauce as it cooks with the butter, giving it body.
- Consomme
- Forms the liquid base of the sauce and supplies its savoury flavour.
- Egg yolks
- Enrich and thicken the sauce, adding body and a velvety texture.
The step that matters
Stir the egg yolks in after boiling stops. Egg yolks set when overheated and can curdle or scramble in a boiling sauce. Removing the sauce from boiling and stirring quickly keeps the yolks smooth and evenly blended.
