Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Halibut or salmon
Forms the main body of the filling and supplies its flavor.
Milk or cream
Makes a smooth sauce with moisture and richness for the filling.
Butter
Adds fat and flavor to the base of the sauce.
Flour
Thickens the milk into a smooth, spreadable sauce.
Grated cheese
Adds savory flavor and helps the filling become rich and cohesive.
Lemon juice
Adds acidity that brightens the flavor of the fish and sauce.

The step that matters

Gradually stir in the hot milk or cream. Adding the hot liquid slowly to the butter and flour mixture lets the starch disperse evenly. Adding it all at once can form lumps, leaving the sauce grainy instead of smooth.

Swap the parsley

How well each one fits the dish's main ingredients (salmon, milk, butter, flour, pepper, lemon, cheese):

  1. Parsleythe original
  2. Thymefits about as well
  3. Dillfits about as well
  4. Cardamomfits about as well

Fit is the average pairing score against salmon, milk, butter, flour, pepper, lemon, cheese. Candidates are from the same food group and used in at least 100 recipes.
