Ingredients
Directions
Fry the chopped onions in butter over low heat until soft, but do not let them brown.
Add the white sauce and reduce it to a proper thickness.
Stir in the fowl, season with salt, white pepper, sugar, parsley, and mushrooms.
Let it boil, then add the egg yolks and stir well.
Once the eggs have set, pour the mixture onto a dish to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Set the mixture and bind it into a firm, sliceable filling as they cook.
- White sauce
- Provides a thick, creamy base that holds the fowl together.
- Roast fowl
- Supplies the main body and savoury flavour of the filling.
- Butter
- Softens the onions and adds richness and a gentle flavour.
The step that matters
Adding the egg yolks. Egg yolks thicken and set when heated, but if the mixture boils too hard after they go in, they can scramble and turn grainy. Stir well and keep the heat controlled so the filling sets smooth.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, onion, sauce, sugar, parsley, mushroom, egg):
- Capersfits better
- Thymefits better
- Garlicfits better
- White pepperthe original
Fit is the average pairing score against butter, onion, sauce, sugar, parsley, mushroom, egg. Candidates are from the same food group and used in at least 100 recipes.
