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

What each ingredient does

Codfish
Provides the flaky, tender main body of the dish.
Bechamel sauce
Adds creamy moisture that binds the cod flakes together.
Fried bread-crumbs
Adds a crisp, golden contrast to the soft filling.

The step that matters

Warming the cod without breaking the flakes. Overheating or stirring vigorously makes the delicate fish fibers break down and turn dry and mushy. Gentle, thorough warming keeps the flakes intact while heating them through in the sauce.

Flavor stand-ins for the lemon

Fit is the average pairing score against sauce, bread. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
