Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the dish, cooked gently in the covered pan to stay moist.
- Butter
- Adds richness and moisture, and helps the bread crumbs brown in the oven.
- Veal stock or weak gravy
- Provides savory liquid in the pan that becomes the base of the sauce.
- Bread crumbs
- Form a crisp, browned crust over the fish that holds in moisture.
- Parmesan cheese
- Adds savory, salty flavor and body to the sauce as it melts into the gravy.
- Lemon juice
- Adds acidity that brightens the fish and sharpens the sauce.
The step that matters
Thicken the gravy with butter rolled in browned flour. Flour thickens liquid only when it is mixed in evenly and heated; lumps form if the flour-butter is added to hot gravy without being stirred in well. Boiling afterward cooks out the raw flour taste and sets the sauce's body.
