Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce that binds the fish and crumbs together.
- Corn starch or flour
- Thickens the milk into a smooth sauce as its starch swells when heated.
- Cold fresh fish or salt codfish
- Provides the main flavour and bulk of the dish, set in the sauce.
- Butter
- Adds richness and flavour to the sauce and greases the dish.
- Cracker or bread crumbs
- Adds texture and a crisp topping that browns during baking.
The step that matters
Bring the starch mixture to a boil. Starch must be heated to a boil so its granules swell and thicken the milk fully; undercooked starch leaves a thin, pasty sauce that does not set.
Swap the white pepper
How well each one fits the dish's main ingredients (milk, onion, parsley, egg, butter, corn, bread):
- Nutmegfits better
- Thymefits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against milk, onion, parsley, egg, butter, corn, bread. Candidates are from the same food group and used in at least 100 recipes.
