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 heat and enrich its texture.
- Veloute sauce
- Forms the base body and flavour that the rest of the sauce is built on.
- Cream
- Adds richness and a smooth, silky mouthfeel.
- Lemon juice
- Adds acidity that brightens the rich egg and cream mixture.
- Chopped cooked button mushrooms
- Contribute earthy flavour and a soft, meaty bite.
- Shallots
- Add a mild onion-like sweetness and aroma to the sauce.
The step that matters
Gradually stir the egg mixture into the boiling Veloute. Egg yolks can scramble and curdle if they meet hot liquid too quickly. Adding the mixture slowly while stirring evenly shares out the heat, so the yolks thicken the sauce smoothly instead of setting in lumps.
