Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm fish
- Forms the bulk of the pie and provides the main flesh texture.
- Milk
- Forms the liquid base of the white sauce, giving it body once thickened.
- Butter
- Fat that is cooked with flour to make the roux that thickens the sauce.
- Flour
- Starch that thickens the melted butter and milk into a smooth sauce.
- Egg yolks
- Enriches the sauce, adding richness and helping it set softly when baked.
- Onions
- Steeped in the milk to add sweetness and aroma to the sauce.
The step that matters
Stir the mixture until it thickens. Flour must be cooked with the butter and milk until the starch swells and thickens the sauce. Adding the egg yolks to a sauce that is too hot can scramble them, so the sauce should be thickened before the yolks go in.
Swap the onion
How well each one fits the dish's main ingredients (fish, pepper, milk, thyme, parsley, nutmeg, butter):
