Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young button mushrooms
- Provide earthy flavour and tender texture after gentle stewing.
- White veal gravy
- Savoury liquid base that carries the flavour through the whole sauce.
- Flour
- Starch that thickens the gravy into a smooth, lightly body sauce as it heats.
- Egg yolk
- Adds richness and gentle thickening when stirred in at the end.
The step that matters
Stirring in the egg yolk. Egg yolk proteins set when heated, so if the sauce boils after the yolk goes in, it can curdle or scramble. Stir it in just before serving, off the heat or at low heat, to keep the sauce smooth and glossy.
