Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Button mushrooms
- Main ingredient that softens during stewing and releases moisture into the sauce.
- Flour
- Starch that thickens the cooking liquid into a creamy consistency as it heats.
- Butter
- Adds fat and richness, giving the sauce a smooth, rounded flavour and texture.
- Egg
- Forms a liaison that further enriches and thickens the sauce when added at serving.
The step that matters
Adding the egg liaison. Egg proteins set when heated, so the liaison can curdle or turn grainy if the sauce is boiling. Add it off the heat or at low heat, and keep stirring.
