Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body that is stuffed and baked, carrying the filling's flavour.
- Stale bread
- Soaked and squeezed, it adds body and moisture to the stuffing.
- Egg yolks
- Beaten into the stuffing, they bind it and set as it heats and bakes.
- Butter
- Adds richness and fat, softening the onion and carrying flavour through the stuffing.
- Hard-boiled egg yolks
- Mashed with oil and mustard to form a rich, emulsified sauce base.
The step that matters
Sew the fish up with fine twine. If the stuffing is not sealed inside, it can leak or loosen during baking, so the fish must be closed firmly before cooking.
Swap the mustard
How well each one fits the dish's main ingredients (fish, bread, onion, butter, pepper, parsley, egg):
- Potatofits better
- Chivefits better
- Leekfits better
- Mustardthe original
Fit is the average pairing score against fish, bread, onion, butter, pepper, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
