Ingredients
Directions
Make the base
Pour the velouté and jelly broth into a stewpan with mushroom and truffle parings.
Place on high heat and stir until it boils.
Reduce heat, cover, and simmer for about 1 hour.
Remove fat and return to heat, stirring continuously until thickened to a jelly-like consistency.
Finish the sauce
Mix egg yolks and cream, strain, and add to the sauce with butter, stirring well.
Put on moderate heat and stir until it begins to boil, then remove from heat.
Add an equal amount of butter and a little nutmeg, stirring to combine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Velouté
- Forms the thick base that the sauce is built on.
- Jelly broth of poultry
- Adds body and savoury depth, and sets to a jelly-like texture when reduced.
- Egg yolks
- Thicken the sauce as they heat and give it richness.
- Cream
- Adds richness and a smoother, silkier mouthfeel.
- Butter
- Adds fat for a glossy finish and a rounded, rich flavour.
The step that matters
Adding the egg yolk and cream mixture. Egg yolks thicken when heated but can scramble if the sauce is too hot. Keep the heat moderate and stir constantly so the sauce thickens smoothly without curdling.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
