Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turtle steak
- Forms the main body of the dish, becoming tender through long, covered simmering.
- Browned flour
- Thickens the gravy into a smooth sauce when stirred in and heated.
- Veal gravy
- Provides the liquid base and savoury flavour for the fricassée.
- Mushrooms
- Add earthy flavour and moisture after frying in butter.
- Hard-boiled egg yolks
- Enrich the sauce, adding body and a creamy richness.
The step that matters
Boil the gravy for at least 5 minutes after adding the flour paste. Flour starch only thickens fully once heated to boiling and held there, so a brief simmer leaves the sauce thin and possibly tasting of raw flour.
Swap the onion
How well each one fits the dish's main ingredients (veal, butter, mushroom, pepper, flour, lemon, wine):
